The United States and China will hold a delayed top-level diplomatic and security dialogue in Washington on Friday, amid moves to try to resolve a damaging trade war.
US Secretary of State Mike Pompeo, Defence Secretary Jim Mattis, Chinese politburo member Yang Jiechi and Defence Minister Wei Fenghe will take part in the talks, a statement from US State Department said on Monday.
China last month said the two sides had initially agreed "in principle" to hold the second round of diplomatic security talks in October but they were postponed at Washington's request amid rising tensions over trade, Taiwan and the South China Sea.
Monday's announcement came after US President Donald Trump and Chinese President Xi Jinping spoke by telephone last week and cheered world markets by expressing optimism about resolving their trade dispute ahead of a high-stakes meeting at the end of November in Argentina.
On Monday, Trump said China wanted to make a deal and added: "If we can make the right deal, a deal that's fair, we'll do that. Otherwise we won't do it."
Earlier on Monday, Xi promised at the start of a trade expo to lower tariffs, broaden market access and import more from overseas.
Trump and Xi announced the updated negotiation framework last year and the first meeting in the format was held in June 2017 in Washington, when the two sides discussed issues including North Korea and the South China Sea.
Since then relations have soured and they have become embroiled in a major trade war in which the United States has imposed tariffs on $US250 billion worth of Chinese goods and China has retaliated with tariffs on $US110 billion worth of US goods.
Trump has railed against China for what he sees as intellectual property theft, entry barriers to US business and a gaping trade deficit.
He has said that if a deal is not made he could impose tariffs on another $US267 billion of Chinese imports and an across-the-board pressure campaign.
Mattis had been due to hold talks with Wei in Beijing in October, but those plans were up-ended after Washington imposed sanctions on China's People's Liberation Army for buying weapons from Russia.
Mattis did meet Wei in Singapore on October 18 and told him that the world's two largest economies needed to deepen high-level ties to reduce the risk of conflict.
