The Trump administration has been saying that the two countries are engaged in talks to resolve the dispute, but Beijing asserts that no such discussions are happening.

U.S. President Donald Trump asserted in an interview published on Friday that tariff negotiations were under way with China, but Beijing denied any talks were taking place, the latest in a series of conflicting signals over what progress was being made to de-escalate a trade war threatening to sap global growth.

China appears to have quietly rolled back retaliatory tariffs of 125% on some semiconductors made in the United States, according to details provided to CNN on Friday by three import agencies in the southern technology hub of Shenzhen.

An American business group said Chinese officials had surveyed companies about American products that are crucial to their supply chains.

While Beijing has consistently said it is open to talks, Chinese officials have struggled to understand the Trump administration’s demands.
