The United States wants trade talks in Beijing this weekend to result in structural changes to China's economy, in addition to increased Chinese purchases of American goods, U.S. Treasury Secretary Steven Mnuchin said on Saturday.

U.S. Commerce Secretary Wilbur Ross arrived in Beijing on Saturday with an interagency team of U.S. officials for talks on long-term purchases of U.S. farm and energy commodities, just days after Washington renewed its threats to impose tariffs on Chinese goods.

The purchases are partly aimed at shrinking the $375 billion U.S. goods trade deficit with China.
