(Bloomberg) -- Donald Trump complained that China hasn’t increased its purchases of American farm products, a promise he said he had secured at a meeting with the country’s president, Xi Jinping, at the Group of 20 summit last month.

Xi and Trump agreed to restart trade talks between their countries at the meeting, and the U.S. president said he would hold off on imposing additional tariffs on Chinese imports. Trump also claimed Xi had agreed that China would buy large amounts of U.S. agricultural goods.

But Chinese official media said only that Trump hoped China would import more American goods as part of the trade-war truce. The two sides didn’t release any official documentation of Trump and Xi’s agreement, leaving confusion about how the countries would proceed.

U.S. Trade Representative Robert Lighthizer and Treasury Secretary Steven Mnuchin spoke on the phone with their Chinese counterparts this week, marking the first high-level contact following the G-20 meeting.

The American officials spoke to Chinese Vice Premier Liu He and Commerce Minister Zhong Shan on Tuesday, according to an emailed statement from a U.S. government official who declined to be identified. Both sides will continue these talks as appropriate, the official said, without offering more details on the next steps.
