China and Vietnam will manage and properly control their maritime disputes, avoiding actions to complicate or widen them, so as to maintain peace in the South China Sea, the two nations said in a joint communique China released Monday.

Vietnam is the Southeast Asian country most openly at odds with China over the waterway since the Philippines pulled back from confrontation under President Rodrigo Duterte.

After what China said were "positive" talks on the South China Sea last week between President Xi Jinping and Vietnamese President Tran Dai Quang, the joint statement stressed the need to control differences.
