President Donald Trump on Monday intensified the ongoing trade standoff with China by threatening to impose a fresh wave of 50% tariffs unless Beijing rolls back its latest retaliatory duties. The move signals a sharp escalation in an already volatile global trade environment that has left markets shaken.

Trump announced that if China fails to revoke its newly imposed 34% retaliatory tariff by Tuesday, the United States will respond with heightened duties starting Wednesday. He also stated that all scheduled trade discussions with Chinese officials would be canceled, even as talks with other nations would be prioritized and fast-tracked.

In a strongly worded message posted on Truth Social, Trump criticized China for what he called “record-setting tariffs,” along with “non-monetary barriers, illegal corporate subsidies, and long-term currency manipulation.” He warned that any country retaliating against the U.S. with added tariffs would face immediate and harsher economic consequences.

“China issued retaliatory tariffs of 34%, on top of long-standing abusive trade practices,” Trump wrote. “Despite clear warnings, they continue to exploit trade through manipulation and protectionism. If they do not rescind the 34% increase by April 8th, the United States will impose additional tariffs of 50% effective April 9th.”

Trump also confirmed that trade negotiations with Beijing would be halted, while trade talks with other interested countries would proceed without delay.

This latest development reflects a hardening of the U.S. stance and raises the stakes for global commerce, especially between the world’s two largest economies.
