BEIJING – China imposed fines and sanctions against two US defence companies in a further escalation of tensions between the worlds two biggest economies.

Lockheed Martin Corporation and a subsidiary of Raytheon Technologies Corp were added to a list of unreliable entities due to their participation in arms sales to Taiwan, Chinas Ministry of Commerce said Thursday.

The companies were fined twice the contract value of their arms sales to Taiwan since September 2020 when the list first came into effect and would be required to pay within 15 days, according to the statement.

China regards Taiwan as a renegade province to be reunified, by force if necessary. Beijing has long complained about the US supplying weapons to the island.

A day before the announcement, China had warned that it would hit the US with counter-measures over violations of its sovereignty, and on Thursday blamed the US for jeopardising ties by overreacting in the ongoing spat over a balloon.

However, the subsequent announcement of sanctions may further escalate that dispute.

Washington contended that the balloon was spying and shot it down, while China claims it was a civilian airship collecting weather data that went off course.

Its unclear if the latest sanctions will prevent a meeting between US Secretary of State Antony Blinken and Mr Wang Yi, Chinas top diplomat, on the sidelines of the Munich Security Conference this week.

Mr Blinken cancelled a planned trip to Beijing this month when the balloon controversy erupted.

Its a message to the US, but also for domestic consumption – to demonstrate Chinas tough position, said Dongshu Liu, an assistant professor specialising in Chinese politics at the City University of Hong Kong.

The economic consequences might not be as strong as the political ones – those companies dont do business in China. They may face some limitation as a result of these new sanctions, but still, its largely politically symbolic.

As with previous sanctions announced against the firms and other US defence companies, these measures are likely to be largely symbolic, given both have little direct exposure to China.

An e-mail to Raytheon outside of business hours went unanswered, as did calls to Lockheed Martin.

If they dont pay the fines within 15 days the ministry may increase the fines, the statement said.

In addition, it will cancel and prohibit work and residence permits for the companies senior managers and ban them from entry into the country.

This action shows that Chinas retaliation remains very targeted and refrained, responding to US arms sales towards Taiwan, over which China has lodged its protest many times in the past, said Mr Feng Chucheng, a Beijing-based partner at independent consultancy Plenum.

China is not weaponising its sanctions, which is consistent with Chinas longstanding policies.

China has threatened sanctions against US entities that damage its national security in the past.

In 2020 it said it would impose unspecified sanctions on Boeing Co.s defence unit, Lockheed Martin, and Raytheon after the US State Department approved arms sales to Taiwan.

Last September, Beijing said it was sanctioning two top executives at Boeing and Raytheon over the biggest US weapons deal with Taiwan in almost two years, but didnt provide details on the measures.

Naming two already sanctioned companies onto the list for the first time actually proves that Mofcom wants to take it slow and experiment with how to implement the new unreliable entity list, according to Mr Andy Chen, a senior analyst with Beijing-based consultancy Trivium China.

The list was created in haste as a response to USs long-arm jurisdiction but Mofcom wasnt ready to deploy it at the time because it lacked the experience – and probably personnel – to carry it out.BLOOMBERG More On This Topic China plans sanctions on CEOs of Boeing Defence, Raytheon over Taiwan arms sale Beijing places sanctions on US arms companies Lockheed and Raytheon
