A Commerce Ministry spokesperson also said China could introduce its own unspecified "countermeasures" if the US President carries out his threat, adding it was "not afraid" of a possible trade war. On Friday, Trump hit back at Beijing's move to tighten its rules for exports of rare earths, accusing China of "becoming very hostile" and trying to hold the world "captive". He also threatened to pull out of a meeting with China's President Xi Jinping scheduled for later this month. Trump's comments on Friday rattled financial markets, with the S&P 500 share index closing down 2.7%, its steepest fall since April. The president's words renewed fears of a trade war between the US and China.

In May, the two sides had agreed to drop triple-digit tariffs on each other’s' goods. which had raised the prospect of trade halting between the two countries. This left US tariffs on Chinese goods facing an added 30% levy compared with the start of the year, while US goods entering China face a 10% tariff. China's latest remarks – released by the Commerce Ministry in the form of written responses to journalist's questions – echoed language from the height of the recent trade conflict.

They criticised US export restrictions on chips and semi-conductors as well as defending China's own export controls on rare earths as "normal actions" to safeguard national security and that of all nations. The spokesperson said that for "a long time", the US had "overstretched the concept of national security, abused export control measures" and "adopted discriminatory practices against China".  "Resorting to tariff threats is not the right way to engage with China," the spokesperson said. "China's position on a tariff war has always been consistent: we do not want one, but we are not afraid of one." (BBC)
