Chinese leader Xi Jinping and US President Donald Trump are expected to meet at the G20 Summit in Hangzhou on Tuesday.
The meeting is part of the G7 summit in Germany on Wednesday and is likely to be the first of its kind.
Mr Xi will be meeting Mr Trump after the G8 Summit in Northern Ireland on Saturday, and then his second G20 summit on Tuesday in Turkey.
On Friday, China will host the first ever bilateral summit between the two leaders.
The leaders will discuss the situation in the South China Sea and North Korea’s nuclear programme, the latter of which China has been accused of trying to build.
The G7 meeting in Hangzhou was held on a Friday evening.
China’s official Xinhua news agency has quoted a senior official as saying the meeting is expected to last for two hours and will focus on “strengthening bilateral relations and promoting joint projects”.
A source in the US State Department said Mr Trump would not attend the meeting, adding: “It’s the first time we’ve seen the president of the United States come to China.”
