Trump and Chinese President Xi Jinping plan to meet on the sidelines of a G20 summit, in Argentina at the end of November for a high-stakes talk.

The United States and China must work to ensure that talks to take place between the two countries' leaders at this month's G20 summit go well, said a senior Chinese diplomat, amid a bitter trade war.

The two countries have slapped tariffs on hundreds of billions of dollars of each other's goods and U.S. President Donald Trump has threatened to set tariffs on the remainder of China's $500 billion-plus exports to the United States if the trade dispute cannot be resolved.

Trump and Chinese President Xi Jinping plan to meet on the sidelines of a G20 summit, in Argentina at the end of November for a high-stakes talk.

The two sides should "properly manage differences and carefully prepare to ensure positive results in the Argentine meeting," said politburo member Yang Jiechi in a statement posted on the official Ministry of Foreign Affairs website.

"China is committed to working with the U.S. to achieve a no-confrontational, conflictless, mutually respectful co-operation in which both sides win," added Yang.

"Both sides should seek an appropriate solution through equal and mutually beneficial negotiations," said Yang, adding that the essence of China, U.S. trade and economic ties is mutually beneficial.
