U.S. President Donald Trump and his Chinese counterpart Xi Jinping held a phone call on Monday, state media in Beijing said, following their October meeting in South Korea.

Trump announced the plans after a call with the Chinese president that he said was focused on the Russia-Ukraine war and agricultural products like soybeans, a major U.S. export.

The two leaders discussed trade, Ukraine and Taiwan in their first phone call since meeting in South Korea last month.

President Trump said he accepted an invitation from Chinese President Xi Jinping to visit China in April and invited Xi to the US for a state visit.

U.S. President Donald Trump has targeted top economic rival China with a cascade of tariffs on imports worth billions of dollars as he tries to narrow a trade deficit, bring home lost manufacturing and cripple the fentanyl trade.

When Xi Jinping and Donald Trump sat down in South Korea last month to discuss a pause in their trade war, Taiwan surprisingly didn’t come up. Now the biggest flashpoint between the US and China is firmly back on the agenda.

President Donald Trump says he will visit Beijing in April and host China’s President Xi Jinping for a state visit later next year.

Trump announced a deal on soybeans—the most valuable U.S. agricultural export—on October 30, after talks with Xi in South Korea, to the relief of U.S. farmers. Greater Chinese purchasing of U.S. farm produce will boost U.S. exports as well as support for Trump in rural America.
