The federal aid comes after China boycotted American farm products in retaliation for U.S. tariffs.

The Treasury Secretary said on Sunday he recently shed his holdings to comply with his federal ethics agreement.

In an unusual move, Xi Jinping, the leader of China, called President Trump. The two spoke about trade, Taiwan and Ukraine, according to separate official statements.

By withholding soybean purchases and rare-earth exports, China extracted relief from U.S. tariffs and delayed export controls, without conceding much in return.

The Trump administration is hailing a potential deal that may return the U.S.-China relationship to where it was before the president began a trade war against Beijing.
