The Thucydidean trap closes

China is beginning to wield its economic power:

The Chinese foreign ministry has warned that American firms would be banned from doing business in China if they are involved in any arms deals with Taiwan.

“In order to safeguard national interests, China will impose sanctions on US companies involved in arms sales to Taiwan,” foreign ministry spokesman Geng Shuang told reporters on Monday. “The Chinese government and Chinese companies will not cooperate and do business with these US firms,” he added.

Answering reporters’ questions, Geng said the details about such companies and the timeline of any penalties against them will not be disclosed at present.

As the world’s sole economic superpower, the USA has been throwing its weight around this way for decades. But now China has the ability to do so as well, and due to its much larger population and larger economy (in PPP terms), it will likely be able to wield this power more effectively than the USA in the future.
