The first state visit of US President Donald Trump to China, which starts on Wednesday, is expected to be a "historic" success with joint efforts made by the two nations, senior diplomats of both sides said.

The three-day visit will provide opportunities for President Xi Jinping and Trump to exchange in-depth views on issues that concern both sides, Foreign Ministry spokeswoman Hua Chunying said at a regular news conference on Tuesday.

The visit is of great significance in pushing forward the steady development of Sino-US relations in the new era and promoting the prosperity of not only the Asia-Pacific region but also the world, she said.
