BEIJING Chinas economic growth in 2022 slumped to one of its worst levels in nearly half a century as the fourth quarter was hit hard by stringent Covid-19 curbs and a property market slump, raising pressure on policymakers to unveil more stimulus this year.

The quarterly growth and some of the December indicators such as retail sales beat market expectations, but analysts noted that the overall economic impulse across China remained weak and highlighted the challenges facing Beijing after it abruptly dropped its zero-Covid policy last month.

Gross domestic product (GDP) grew 2.9 per cent in the October-to-December period from a year earlier, data from the National Bureau of Statistics (NBS) showed on Tuesday, slower than the third quarters 3.9 per cent pace. The rate still exceeded the second quarters 0.4 per cent expansion and market expectations of a 1.8 per cent gain.

Beijings sudden relaxation of stringent anti-virus measures has boosted expectations of an economic revival this year, but it has also led to a sharp rise in Covid-19 cases that economists say might hamper near-term growth. A property slump and weak global demand also mean a rebound in growth will be heavily reliant on shell-shocked consumers.

Chinas 2023 will be bumpy; not only will it have to navigate the threat of new Covid-19 waves, but the countrys worsening residential property market and weak global demand for its exports will also be significant brakes, Mr Harry Murphy Cruise, an economist at Moodys Analytics, said in a note.

For 2022, GDP expanded 3 per cent, badly missing the official target of around 5.5 per cent and braking sharply from the 8.4 per cent growth in 2021. Excluding the 2.2 per cent expansion after the initial Covid-19 wave hit in 2020, it is the worst showing since 1976 the final year of the decade-long Cultural Revolution that wrecked the economy.

Asian shares dropped after the Chinese data, while the renminbi skidded to a one-week low.

Activity data in December surprised broadly to the upside but remains weak, particularly across demand-side segments such as retail spending, Ms Louise Loo, a senior economist at Oxford Economics, said in a note.

(The) data so far supports our long-held view that Chinas reopening boost will be somewhat anaemic at the beginning, with consumer spending being a key laggard in the initial stages.

A Reuters poll forecast growth to rebound to 4.9 per cent in 2023 as Chinese leaders move to tackle some key drags on growth the zero-Covid policy and a severe property sector downturn. Most economists expect growth to pick up in the second quarter.

On a quarterly basis, GDP stalled, coming in at zero growth in the fourth quarter, compared with growth of 3.9 per cent in July to September, highlighting underlying weakness across many sectors.

Beijings lifting of Covid-19 curbs has seen businesses struggling with surging infections, suggesting a bumpy recovery in the near term.

The ongoing exit wave on the back of Chinas faster-than-expected reopening has taken a heavy toll on economic activity in recent months due to surging infections, a temporary labour shortage and supply chain disruptions, economists at Goldman Sachs said, noting the annual contractions in output of both steel products and cement in December.

Factory output grew 1.3 per cent in December from a year earlier, slowing from the 2.2 per cent rise in November, while retail sales, a key gauge of consumption, shrank 1.8 per cent last month, extending Novembers 5.9 per cent drop.

The central bank is also expected to steadily ease policy this year.

China is likely to aim for economic growth of at least 5 per cent in 2023 to keep a lid on unemployment, policy sources said.

Chinas property industry was among the biggest drags on growth. Investment in the sector fell 10 per cent year on year in 2022, the first decline since records began in 1999, and property sales slumped the most since 1992, NBS data showed, suggesting that government support measures were having minimal impact so far.

The authorities have rolled out a flurry of support policies targeting home buyers and property developers in recent weeks to relieve a long-running liquidity squeeze that has hit developers and delayed the completion of many housing projects.

Adding to the challenges facing the economy and the government, Chinas population in 2022 fell for the first time since 1961, the NBS data showed, a historic turn that is expected to mark the start of a long period of decline in its citizen numbers and see India become the worlds most populous nation in 2023.

The population will likely trend down from here in the coming years. This is very important, with implications for potential growth and domestic demand, said Pinpoint Asset Management chief economist Zhang Zhiwei.

Going forward, demographics will be a headwind. Economic growth will have to depend more on productivity growth, which is driven by government policies.

No job for Tom Tugendhat in Kemi Badenoch's shadow cabinet as Chris Philp appointed shadow home secretary

Tom Tugendhat is not serving in Kemi Badenoch’s shadow cabinet, it has been revealed – as the new Tory leader continued her appointments today.

Former Home Office minister Chris Philp has been awarded the job of shadow home secretary, the last of the key posts to be announced.

A Conservative source told Sky News Mr Tugendhat was offered a job and turned it down.

Unveiling a host of appointments today, Ms Badenoch, who was elected leader of the Conservative Party last weekend, confirmed that Ed Argar would be the shadow health secretary, while James Cartlidge will take on the role of shadow defence secretary.

Former business minister Kevin Hollinrake will shadow Angela Rayner on the housing brief, while Victoria Atkins will take on the role of shadow environment secretary.

Claire Coutinho, who was the energy secretary under Rishi Sunak, will continue in the opposition version of the role.

More on Conservatives

Helen Whately has been appointed shadow work and pensions secretary and Andrew Griffith, the former economic secretary to the Treasury, is the new shadow business and trade secretary.

Ms Badenoch, who became Conservative leader on Saturday, started officially appointing her shadow cabinet on Sunday evening.

Yesterday Dame Priti Patel made a comeback to frontline politics after the new Conservative leader appointed her as shadow foreign secretary.

Former shadow work and pensions secretary Mel Stride, who ran in the Tory leadership race and is considered more of a moderate than Ms Badenoch, was also made shadow chancellor.

The move has been interpreted as Ms Badenoch making an effort to unite the party following its bruising election defeat, which saw it reduced to just 121 seats.

Badenoch: ‘It is time to renew’

Robert Jenrick, who lost out to Ms Badenoch in the Tory leadership race, is the new shadow justice secretary, while Laura Trott, who previously served as chief secretary to the Treasury, was appointed shadow education secretary.

Now the Conservatives are in opposition, the shadow cabinet’s role is to scrutinise the policies and actions of the government and offer alternative policies.

Other roles that have been confirmed today include Stuart Andrew as shadow culture secretary, Gareth Bacon as shadow transport secretary, Andrew Bowie as shadow Scotland secretary, Alex Burghart as shadow Chancellor of the Duchy of Lancaster and Shadow Secretary of State for Northern Ireland and Mims Davies as shadow Wales secretary and shadow minister for women.

Former transport minister Jesse Norman has been appointed as shadow leader of the Commons while Richard Fuller is the new shadow chief secretary to the Treasury and Alan Mak is the new shadow science secretary.

During the Conservative Party leadership race, Ms Badenoch suggested that all six MPs who ran against her for the top job – Mr Jenrick, Mr Tugendhat, Mr Stride, Ms Patel and James Cleverly – would be offered a job in her shadow cabinet.

Mr Cleverly, who came third in the leadership race, said on Friday he would not be joining Ms Badenoch’s top team.

It is understood Ms Badenoch will appoint the remainder of the team later in the week and on a rolling basis.

Geodynamic Model Reveals Erosion Process of North China Craton

Researchers at the China University of Geosciences in Beijing, led by Professor Shaofeng Liu, have shed light on the mysterious transformation of the North China Craton (NCC). This research, published in Nature Geoscience, presents a breakthrough model that explains the processes behind the craton’s gradual erosion, which began in the Mesozoic era. Using detailed mantle-flow modelling, Liu’s team has traced how tectonic forces deep within the Earth have destabilised this ancient portion of continental crust, challenging long-held assumptions about craton stability.

Reconstructing Ancient Tectonic Forces

In a recent study published in Nature Geosciencethe model suggests subducted beneath the Eurasian plate where the NCC is located. Unlike typical subduction, this plate didn’t immediately sink into the mantle. Instead, it slid horizontally under the NCC’s crust, weakening its foundation in a process known as flat-slab subduction. Using seismic and stratigraphic data, the team reconstructed this tectonic behaviour, revealing how the unusual movement triggered chemical reactions that steadily eroded the NCC’s once-stable base.

Three Stages of Deformation

The research identifies three key stages in the NCC’s deformation. First, as the Izanagi plate began to subduct, it exerted horizontal pressure that altered the composition of the NCC’s foundation. In the second stage, the plate eventually rolled back, sinking deeper and creating a thinning effect on the lithosphere. This rollback phase also caused surface uplift and the formation of rift basins. The final stage saw the development of a “mantle wedge”—a zone of partially melted material—between the sinking plate and the craton, further eroding the base and promoting volcanic activity.

Implications for Geological Understanding

This study provides a more nuanced view of how tectonic and mantle forces interact to erode stable crustal structures over time. Liu’s model offers insight into the NCC’s transformation and makes our understanding of craton stability better, with practical implications for exploring mineral deposits essential to technology. The research paves the way for future studies on the complex life cycles of Earth’s crustal plates, offering a window into ancient geological processes that shape the modern landscape.

Researchers Develop Cell-Size Wearable Devices to Restore Neuron Function

Scientists at the Massachusetts Institute of Technology (MIT) have unveiled groundbreaking cell-wearable devices that could transform the treatment of neurological disorders, including multiple sclerosis (MS). These micro-scale devices, which wrap around individual neurons, mimic the function of natural myelin and restore the electrical signalling disrupted by neurodegenerative diseases. Battery-free and activated by light, the devices offer a new way to monitor and potentially modulate neuron activity within the body.

Synthetic Myelin for Damaged Axons

As per the report by Neuro Science News, these tiny devices are crafted from a soft polymer that rolls and adheres to axons and dendrites when exposed to specific light wavelengths. This unique action allows the device to envelop neuronal structures without damaging delicate cellular components. According to Deblina Sarkar, head of MIT’s Nano-Cybernetic Biotrek Lab, this design is a step towards creating symbiotic neural interfaces that work at a cellular level. “Our technology allows intimate interfaces with neurons, adapting closely to their complex shapes,” Sarkar explains. By wrapping around axons—the neural “wiring” responsible for transmitting electrical impulses—the device can act like synthetic myelin, potentially restoring functions in damaged neurons.

Advances in Microelectronics

To create these wearables, researchers use azobenzene, a light-sensitive material. When exposed to specific light wavelengths, azobenzene films form microtubes that snugly wrap around neuronal structures. Lead author Marta J. I. Airaghi Leccardi, now a Novartis Innovation Fellow, highlights that the team developed a fabrication technique scalable enough to produce thousands of these microdevices without a semiconductor cleanroom. “This advancement means we can potentially produce cell-wearables in large quantities for therapeutic applications,” says Leccardi.

Future Applications and Possibilities

MIT researchers are optimistic about the potential to integrate these devices with advanced sensors, which could open new pathways for non-invasive brain treatments. The devices may one day help clinicians and researchers monitor electrical, optical, and even thermal signals from neurons, offering a deeper understanding of brain function. Flavia Vitale, associate professor at the University of Pennsylvania, called the research “an exciting foundation” for future in vivo applications, where the devices might aid in treating neurodegenerative diseases more effectively.
