BEIJING - President Hu Jintao on Wednesday pledged to further political and economic ties with Cameroon as the two countries are celebrating the 40th anniversary of diplomatic ties.

"Chinese-Cameroonian ties have endured the test of time and the twist-and-turns of international circumstance," Hu said during talks with Cameroonian President Paul Biya.

He underlined the close contact between the leaderships, enhanced political mutual trust, expanding trade and economic cooperation and sound coordination and cooperation on international and regional issues.

"China appreciates Cameroon's long-term adherence to the one-China policy," Hu said at the Great Hall of the People in downtown Beijing.

He urged the two sides to enhance dialogue and cooperation between leaders, legislatures, government branches and ruling parties, and coordination on global issues like climate change, food security and poverty relief.

Hu also called on the two sides to bolster cooperation in energy, natural resources, infrastructure construction and agriculture, offering help for the central African state's sustainable development.

He suggested the two states advance their traditional friendship and expand cooperation in culture, education, human training, health care and tourism.

Biya hailed the development of bilateral ties since the two states established diplomatic relations in 1971, reiterating that Cameroon will stick to the one-China policy.

He also vowed to enhance cooperation in various fields.

Biya became president in 1982, and this is his fifth visit to China since he took office.
