Beijing. China on Sunday accused the United States of “double standards” after President Donald Trump threatened to impose another 100% tariffs on the world’s second-largest economy.

Trump on Friday announced that he would re-intensify his trade war, saying China had imposed “extraordinarily aggressive” export sanctions related to rare earth elements. He also threatened to cancel his next meeting with Chinese President Xi Jinping with a decision to impose new tariffs and curb exports of “critical software” from November 1.

On Sunday, China’s commerce ministry reacted strongly to Trump’s tax threat, calling it a “clear example of double standards”. The ministry reminded that Washington has been taking economic pressure measures against Beijing since September, saying that “the threat of high tariffs every time is not the right way to deal with China.” ’

Trump has imposed a 30 percent US tariff on Chinese goods, while China is retaliating by imposing a 10 percent tariff, accusing China of engaging in fentanyl trade and unfair trade practices.

Rare earth elements have been a major issue in recent trade talks between the two superpowers. These elements are essential in products ranging from smartphones, electric vehicles, military equipment to renewable energy technologies. China dominates the global production and processing of these minerals.

On Thursday, China announced new export controls on technology used to extract and process critical minerals. Trump responded by using his Truth Social platform to accuse China of being “extremely hostile” and “trying to hold the world hostage”.

The US leader has also threatened to pull out of a planned meeting with Xi at the Asia-Pacific Economic Cooperation (APEC) summit in South Korea later this month. It was expected to be the first face-to-face meeting between the two leaders since Trump returned to power in January.

A few months ago, Beijing and Washington agreed to an uneasy truce in the trade war. However, recent developments have rekindled tensions.

On Friday, China announced that it would impose “special port tariffs” on ships built and operated in the United States, as a “defensive measure”. China said the move was in retaliation for the US tariffs on its ships, which it said had “seriously harmed China’s interests”.

The U.S. announced the tariffs in April to revive its own shipbuilding industry. The industry has been dominated by China and other Asian countries for decades.
