"The maritime issue is highly complicated and sensitive, which requires negotiations to manage and control differences," Yu said.

"Megaphone diplomacy can only trigger volatility of the public opinion, which should be avoided by both sides," he added.

Yu vowed to make joint efforts with Vietnam to celebrate the 65th anniversary of bilateral diplomatic ties next year, in order to lay a solid foundation for future development of relations.

"The CPPCC is willing to work closely with the VFF to earnestly fulfill the MoU regarding our cooperation from 2014-2019," he said.

Trong said Vietnam pays close attention to China's economic and social development, and considers it as Vietnam's opportunity.

The CPV admires the CPC's progress in party building and anti- corruption campaign, Trong said, calling on the two parties to share experience in governance, and boost high-level exchange of visits and cooperation in various areas.

President Sang told Yu that Vietnam always gives priority of its foreign policy to its comprehensive strategic cooperative partnership with China, vowing joint efforts with China to cement political trust and pragmatic cooperation.

Prime Minister Dung said Vietnam is ready to join hands with China to properly settle maritime disputes in a candid and friendly spirit, and promote substantial progress in their negotiations regarding the maritime demarcation of the bay mouth of Beibu Gulf.

During his stay, Yu visited the late Vietnamese leader Ho Chi Minh's Mausoleum and witnessed the launch of a Confucius Institute at Hanoi University.
