Growing distrust between the United States and China has slowed the once steady flow of Chinese cash into America, with Chinese investment plummeting by nearly 90 percent since President Trump took office.

Some Chinese enterprises have inquired with U.S. exporters about the purchase of agricultural produce and applied for the lifting of tariffs on the products in accordance with the regulations of the Customs Tariff Commission of the State Council, Chinese authorities said Sunday.

U.S. and Chinese trade officials held a “constructive” phone conversation on Tuesday, White House economic adviser Larry Kudlow said, marking a new round of talks after the world’s two largest economies agreed to a truce in a year-long trade war.

Top American and China negotiators are set to speak this week but disagreements threaten to bog down discussions.

At their Osaka meeting, Trump and Xi agreed to restart trade talks and work to improve US-China ties. Trump also stated he would add no additional tariffs to Chinese goods. The meeting demonstrates the continued importance of dispute management between the two economic powerhouses.

Existing U.S. tariffs will have to be removed if there is to be a trade deal between Beijing and Washington, China’s commerce ministry said.

Top representatives from the United States and China are arranging to resume talks next week to try to resolve a year-long trade war between the world’s two largest economies, Trump administration officials said on Wednesday.

Both China and the United States should make compromises in trade talks, Chinese Vice Commerce Minister Wang Shouwen said on Monday, ahead of a much anticipated meeting between the Chinese and U.S. presidents at this week’s G20 summit in Japan.

The benefits of Sino-US trade—new jobs, more efficient division of labor, an engine for the world economy—have seemingly been forgotten. But all is not lost. If China and the US can reconnect, new opportunities beckon: in infrastructure, energy, tech, climate change, and beyond.

In recent years, China has shown restraint and cooperation in working with America. But US leaders must realize that China’s history of resisting external pressure means it will never abandon its development path to please another country.
