The president expressed sincere sympathy for Tonga's suffering due to Cyclone Gita last month.

China and the Pacific island nations including Tonga are good friends and partners, Xi said, adding that the Communist Party of China's 19th National Congress has proposed to build a new type of international relations with the characteristics of mutual respect, justice and win-win cooperation.

The king of Tonga expressed congratulations on the success of the CPC's 19th National Congress.

Calling Xi a leader with great vision and wisdom, Tupou VI said he believed that China will produce great achievements under Xi's leadership.

"I appreciate your visionary and talented leadership. I have just finished reading your second book on the governance of China. I thought it would be heavy going, but it is very easy to understand," he said.

China and Tonga share the vision of a new type of international relations and also to build a community, he added.

Tonga firmly supports the one-China policy, and is willing to enhance cooperation with China in trade, infrastructure construction, tourism and regarding the Belt and Road Initiative, he said.
