WASHINGTON (AP) -- U.S. Treasury Secretary Scott Bessent said in a Tuesday speech that the ongoing tariffs showdown against China is unsustainable and expects a "de-escalation" in the trade war between the world's two largest economies.

But in a private speech in Washington for JPMorgan Chase, Bessent also cautioned that talks between the United States and China had yet to formally start. Trump placed import taxes of 145% on China, which has countered with 125% tariffs on U.S. goods. Trump has placed tariffs on several dozen countries, causing the stock market to stumble and interest rates to increase on U.S. debt as investors worry about slower economic growth and higher inflationary pressures.

"I do say China is going to be a slog in terms of the negotiations," Bessent said according to a transcript obtained by The Associated Press. "Neither side thinks the status quo is sustainable."

The S&P 500 stock index rose after Bloomberg News initially reported Bessent's remarks.

The Trump administration has met for talks with counterparts from Japan, India, South Korea, the European Union, Canada and Mexico, among other nations. But Trump has shown no public indications that he plans to pullback his baseline 10% tariff, even as he has insisted he's looking for other nations to cut their own import taxes and remove any non-tariff barriers that the administration says have hindered exports from the U.S.
