Chinese state media on Monday lambasted U.S. President Donald Trump’s trade policies in an unusually personal attack, and sought to reassure investors anxious about China’s economy as growth concerns battered its financial markets.

China’s strictly controlled news outlets have frequently rebuked the United States and the Trump administration as the trade conflict has escalated, but they have largely refrained from specifically targeting Trump.

The latest criticism from the overseas edition of the ruling Communist Party’s People’s Daily newspaper singled out Trump, saying he was starring in his own “street fighter-style deceitful drama of extortion and intimidation”.

Trump’s desire for others to play along with his drama is “wishful thinking”, a commentary on the paper’s front page said, arguing that the United States had escalated trade friction with China and turned international trade into a “zero-sum game”.
