President Donald Trump says China and the U.S. have agreed to more tariff talks amid trade standoff and concerns over rare earths.

News of the call came as new data showed U.S. goods imports dropped significantly in April as sweeping tariffs rolled out.

Earlier this week, China hit back on Trump’s claims the Asian country was in breach of a new trade agreement, struck last month following talks held in Geneva, Switzerland, countering that the U.S. itself was undermining the deal with new sanctions.
