China and the U.S. hope to reach an agreement on lowering import taxes soon, a Chinese government spokesperson said Thursday, fueling expectations that an announcement could come when the leaders of the two countries meet in two weeks.

Negotiators are striving to implement reciprocal tariff reductions on $30 billion of goods "at an early date," Commerce Ministry spokesperson Huang Ling said at a weekly briefing.

She did not elaborate. U.S. President Donald Trump and Chinese leader Xi Jinping are expected to meet in Washington on Sept. 24 for what will be their third face-to-face talks in the past year. Both governments characterize the top leader talks as a way to stabilize relations in an era of competing interests between the world's two largest economies.

"Leaders’ diplomacy plays an irreplaceable strategic guiding role in China-U.S. relations,” Chinese Foreign Ministry spokesperson Guo Jiakun said Thursday.

Trump and Xi agreed at their previous meeting in May in Beijing to launch a U.S.-China Board of Trade that would manage trade between the two countries, along with a parallel Board of Investment. The agreements came after a truce was reached in a blistering tariff war in which Trump hiked tariffs on Chinese imports to extremely high levels and China responded in kind.
