China and Myanmar exchanged a number of cooperation documents covering such areas as politics, trade, tourism, investment and people-to-people communications amid President Xi Jinping's state visit on Saturday.

The exchange ceremony was attended by Xi and Myanmar State Counsellor Aung San Suu Kyi. The two countries issued a joint statement the same day.

Hailing the corridor as a flagship project for Belt and Road cooperation between the two countries, Xi said the two sides have initiated construction and the project should bring benefits to the people as soon as possible.

Xi pointed out China welcomes Myanmar to expand exports to China, and Chinese companies are encouraged to increase investment in Myanmar.

Aung San Suu Kyi welcomed Xi's state visit to Myanmar, saying the visit was a milestone for bilateral relations.

Myanmar would like to promote the building of the Myanmar-China Economic Corridor and enhance cooperation in transport, energy, production capacity, humanitarian and cultural exchanges, border areas and regional affairs, she said.
