BEIJING, Sept. 5 (Xinhua) -- Chinese President Xi Jinping on Tuesday sent a congratulatory message to Arif Alvi on his election as Pakistan's new president.

China and Pakistan are good neighbors, good friends and good brothers that treat each other with all sincerity and share weal and woe, and the friendship between the two countries has remained solid and kept growing despite the fluctuating international situation, Xi said in the message.

Xi recalled that China and Pakistan jointly decided to enhance their bilateral relations to an all-weather strategic cooperative partnership when he visited Pakistan in 2015.

In recent years, with the joint efforts made by both sides, mutual political trust is stronger, and the construction of the China-Pakistan economic corridor is fruitful, which has not only benefited the two countries and the two peoples, but made positive contribution to peace and development in the region, Xi said.

The Chinese president noted that the strategic significance of the China-Pakistan relations is more prominent under the current circumstances, and the two countries should support each other more staunchly and conduct deeper cooperation.

Xi said that he highly values the development of the China-Pakistan relations and is willing to join hands with Alvi to further enhance the all-weather strategic cooperative partnership and build a closer China-Pakistan community of shared future.

Arif Alvi, a senior leader of the ruling Pakistan Tehreek-e-Insaf (PTI), was elected president of the South Asian country on Tuesday, according to a statement from the Election Commission of Pakistan (ECP).
