BEIJING - Chinese President Xi Jinping congratulated Abdelaziz Bouteflika Saturday on being re-elected president of Algeria.

China and Algeria enjoy a deep traditional friendship, and have been good friends, good brothers and good partners since the two countries established diplomatic relations 55 years ago, Xi said in a congratulatory message.

The two countries announced the establishment of a comprehensive strategic partnership in February, which showed the high level of China-Algeria ties and created broader prospects for the development of bilateral relations, Xi said.

"I attach great importance to the development of China-Algeria ties and am ready to make joint efforts with President Bouteflika to consolidate and advance the China-Algeria comprehensive strategic partnership and bring benefit to the two countries and two peoples," Xi said.

Bouteflika won his fourth term as president with more than 80 percent of the vote, Interior Minister Tayeb Belaiz announced on Friday.
