Taiwan’s prime minister has warned that a “return” to China is not an option.

Cho Jung-tai’s remarks came hours after President Xi Jinping mentioned the issue on a phone call with his US counterpart Donald Trump.

Mr Xi had described Taiwan’s return to mainland China as “an integral part of the post-war international order”.

But the island’s democratically elected government has rejected this – describing Taiwan as a “fully sovereign and independent country”.

“For the 23 million people of our nation, ‘return’ is not an option – this is very clear,” Mr Cho added.

China has offered Taiwan a “one country, two systems” model, but this position is not supported by any mainstream political party.

Meanwhile, relations between Beijing and Tokyo recently plunged to fresh lows after Japan’s prime minister suggested any attack on Taiwan would spark a military response.

Sanae Takaichi’s remarks were swiftly denounced by China’s foreign ministry, which said Japan had “crossed a red line that should not have been touched”.

Sun Yun from the Stimson Centre thinktank said: “My best guess is China is worried about the escalation with Japan.

“The reference to Taiwan and the post-World War II order directly points to the spat with Japan over Taiwan.”

The US has not taken a side when it comes to Taiwan’s sovereignty but is opposed to any use of force to seize the territory.

Mr Trump’s administration has also been ambiguous over whether it would deploy US troops if war broke out in the Taiwan Strait.

Yesterday, Taiwan’s defence ministry spotted a single balloon from China flying over the strait and claims this is part of a campaign of harassment by Beijing.

Chinese officials have previously dismissed these complaints, arguing the balloons are for meteorological purposes.

In other developments, Mr Trump has confirmed that he will visit Beijing in April – with Mr Xi set to travel to Washington for a state visit later in 2026.

Relations have improved in recent weeks after the pair met face to face in South Korea, with the US president moving to cut tariffs.

On Truth Social, he wrote: “Our relationship with China is extremely strong!”

The US secretary of state has hailed a “tremendous amount of progress” on peace talks after the US and Ukraine delegations met in Geneva – but said that negotiators would “need more time”.

Marco Rubio said the meetings in Switzerland on Sunday have been “the most productive and meaningful” of the peace process so far.

He said the US was making “some changes” to the peace plan, seemingly based on Ukrainian suggestions, “in the hopes of further narrowing the differences and getting closer to something that both Ukraine and obviously the United States are very comfortable with”.

Mr Rubio struck an optimistic tone talking to the media after discussions but was light on the details, saying there was still work to be done.

“I don’t want to declare victory or finality here. There’s still some work to be done, but we are much further ahead today at this time than we were when we began this morning and where we were a week ago for certain,” Mr Rubio said.

He also stressed: “We just need more time than what we have today. I honestly believe we’ll get there.”

Sky News’ defence analyst Michael Clarke said on the initial US-Russian 28-point peace plan that it was Donald Trump against the world, with maybe only Moscow on his side.

Mr Rubio praised the Ukrainian attitude towards the talks and said Mr Trump was “quite pleased” after he previously said in a social media post that Ukraine’s leaders had expressed “ZERO GRATITUDE” for US efforts.

Ukrainian President Volodymyr Zelenskyy said in his nightly address on Sunday that there are signs that “President Trump’s team hears us”.

In a news release on Sunday evening, the White House said the day “marked a significant step forward”.

“Ukrainian representatives stated that, based on the revisions and clarifications presented today, they believe the current draft reflects their national interests and provides credible and enforceable mechanisms to safeguard Ukraine’s security in both the near and long term,” it claimed.

Despite diplomatic progress in Geneva the finish line remains a long way off

We’ve witnessed a day of determined and decidedly frantic diplomacy in this well-heeled city.

Camera crews were perched on street corners and long convoys of black vehicles swept down Geneva’s throughfares as the Ukrainians worked hard to keep the Americans on side.

Secretary of state Marco Rubio did not want to go into details at a press “gaggle” held at the US Mission this evening, but he seemed to think they had made more progress in the last 96 hours than the previous 10 months combined.

The Ukrainian leader Volodymyr Zelenskyy also seemed satisfied enough, posting on Telegram that there were “signals President Trump’s team is hearing us” after a day of “numerous meetings and negotiations”.

That said, we are a long way from the finish line here – something Rubio acknowledged when he said that any proposal agreed here would have to be handed over to the Russians.

At that point, negotiations to stop the war would surely get tougher.

President Putin has shown little or no inclination to stop the conflict thus far.

This, then, is the most important reason the Ukrainians seem determined to keep the Americans on side.

European leaders have presented a counter proposal to the widely criticised US-Russian peace plan, with suggestions including a cap on Ukraine’s peacetime army and readmitting Moscow into the G8.

This will only take place if the plan is agreed to by the US, Russia and Ukraine, and the G7 signs off on the move. Russia was expelled after annexing Crimea in 2014.

The counter proposal also includes US guarantees to Ukraine that mirror NATO’s Article 5 – the idea that “an armed attack against one NATO member shall be considered an attack against them all”.

The initial peace plan was worked up by the White House and Kremlin without Ukraine’s involvement, and it acquiesces to many of Russia’s previous demands.

Footage geolocated by Sky News showed Russian soldiers walking through the Shakhtarskyi neighbourhood on the outskirts of Pokrovsk on Thursday.

The video sheds light on the situation in this key frontline area, as Russian forces slowly encroach on Myrnohrad, the satellite town to Pokrovsk, and one of its last remaining outposts.

Videos geolocated by Sky News show fighting intensifying in recent weeks, as Russian forces attempt to gain control of the towns and their network of road and rail intersections.

Gaining control here would give Russia a base from which to access key cities further north that form part of Ukraine’s “fortress belt”.

Russian forces are advancing from all directions, according to the Institute for the Study of War (ISW), with only one small opening to the northwest of Myrnohrad remaining.

Estimated to be only 3km wide by military experts, this withdrawal corridor is patrolled by Russian drone units which monitor the area for moving vehicles and those who may attempt to leave on foot.

Russian forces have been advancing on Myrnohrad since late October.

Video from a Ukrainian unit in Myrnohad, posted on 29 October, shows a Russian vehicle attempting to enter the town from the northeast. The tank is attacked and soldiers attempting to enter on foot are targeted.

Video posted on 3 November shows Russian forces on the ground in the south of the town.

By 8 November, Russian strikes begin to pummel the northeast of Myrnohrad, the location of many of the town’s high-rise buildings, at that time, held by Ukrainian forces.

George Barros, Russia Team & Geospatial Intelligence Team Lead at ISW, told Sky News that Russian strategy in Pokrovsk has been to erode Ukrainian logistical capacity using drones and artillery over the course of several months.

“After denying supply lines and degrading the frontline forces by essentially cutting them off from behind and starving them out in their positions, then the Russians move forward with their infantry and frontal assaults,” Barros explained.

Capture the flag

For a brief period, it looked as though Russian forces had captured Myrnohrad.

Videos posted on 13 November appeared to show a Russian flag flying over the Myrnohrad mine.

However, video posted the following day showed a Ukrainian drone shooting it down.

Both Russian and Ukrainian forces continue to fight for control of Myrnohrad, with videos posted on the 19 and 20 November showing Russian airstrikes on Ukrainian positions in the town, and Ukrainian drone strikes targeting Russian forces on foot.

While the exact numbers of Russian and Ukrainian forces in the area remains unclear, reports indicate that three key Russian units are active in Pokrovsk and Myrnohrad, and are advancing on the towns from the north and south.

A number of Ukrainian units remain inside the towns, including the 145th Assault regiment and the 32nd, 35th, 38th and 155th Brigades. Reports indicate that more Ukrainian units have been moved into surrounding areas to hold the withdrawal corridor open.

Sky News reached out to the Ukrainian brigades still in Myrnohrad, but they declined to comment, citing military regulations.

Strategic significance

Natia Seskuria, associate international security fellow at the Royal United Services Institute (RUSI), explained that the area is important for the Ukrainians to keep and the Russians to take because of its strategic position.

“Situated at a major road and rail intersection in Donetsk Oblast, Pokrovsk has functioned as a central artery for moving troops, equipment, and supplies to Ukrainian units deployed along the surrounding front.”

Russia “would gain a platform to redirect its offensive efforts toward Ukraine’s principal defensive urban centres… including Kramatorsk and Slovyansk,” Seskuria said.

Ukrainian and Russian soldiers in Pokrovsk have fought intensely and at close quarters over the last month.

In late October US-made Black Hawk helicopters containing specialist troops directed by Ukrainian military intelligence entered Pokrovsk to try to keep the town.

But as Russian troops advance, Myrnohrad is becoming the last stronghold of Ukrainian forces in the area.

Uncertain future

At least up until 12 November, there were still civilians living in Pokrovsk and Myrnohrad, despite strikes on buildings in both cities.

A post made on that day by the Donetsk state regional administration estimated 1,200 people remain living in Pokrovsk and 900 in Myrnohrad.

Evacuation is only possible with the help of the military or police, and it is not clear how many have evacuated in the 11 days since.

Barros of ISW says gaining Pokrovsk would increase Russia’s leverage at the negotiating table.

“If the Russians can successfully convince enough international leaders that, okay, the Russians took Pokrovsk, they’re going to take the next thing, and they’re going take the thing, so now let’s negotiate, then that is a strategic victory for the Russians.”
