AlQa'dah 13, 1432, Oct 11, 2011, SPA -- Chinese President Hu Jintao on Tuesday urged the head of Vietnam's ruling Communist Party, Nguyen Phu Trong, to accept joint development of disputed areas of the South China Sea, dpa reported. "China is willing to jointly develop areas of the South China Sea with Vietnam," state television quoted Hu as telling Trong. The countries should "not allow the maritime issue to affect relations between the two nations and two parties", said Hu, who also heads the Chinese Communist Party. Meetings between leaders of communist neighbours China and Vietnam are normally presented as party-to-party rather than state-to-state. Hu was quoted as saying the two nations should maintain dialogue and prevent their differences from becoming "more complicated". Trong arrived in China earlier Tuesday for a five-day visit timed to coincide with the 20th anniversary of the normalization of diplomatic ties after a brief naval battle over the disputed Spratly Islands in 1988. It is Trong's first trip to China since he became General Secretary of the Vietnamese Communist Party in January, Chinese state media said. China said talks with Vietnam in late June over maritime areas near the Spratlys had eased tension that had built earlier this year. The Chinese Foreign Ministry said the two sides promised to "prevent words and actions that would be detrimental" and agreed to accelerate negotiations on basic principles for resolving maritime disputes.
