Vietnam will stay on guard against and firmly resist any schemes to undermine the Vietnam-China relations, and will never follow other countries in opposing China, Phuc noted.

For his part, Wei said China and Vietnam are a community with a shared future of strategic significance, and have both achieved success in economic development as well as combating the pandemic, demonstrating the strengths of the leadership of the communist parties and the socialist system.

The two sides should implement the consensus reached by the leaders of the two countries, improve strategic communication, enhance political mutual trust and deepen military cooperation to further advance the China-Vietnam comprehensive strategic cooperative partnership, he said.

On the South China Sea issue, China and Vietnam should take a broad and long-term perspective, properly handle differences, plan maritime cooperation well, resolutely stand against the interference from powers outside the region, and jointly protect the peace in the South China Sea.
