China has agreed to buy at least $17 billion of agricultural products annually through 2028 and establish boards of trade and investment, the U.S. said after the leaders of the two nations held a major summit in Beijing.

The two boards form ¡°the cornerstone of this historic agreement¡± between President Donald Trump and Chinese leader Xi Jinping as they work to ¡°optimize¡± trade between the world¡¯s largest economies, the White House said in a fact sheet on Sunday.

One day earlier, the Commerce Ministry in Beijing said both sides would adopt a series of measures, including mutually cutting levies on certain products. China didn¡¯t provide specifics, adding that teams from the two countries were still negotiating details. The White House release was silent on tariffs.
