BEIJING, April 29 -- China and India continued with their three-day meeting on border affairs in Beijing on Tuesday, said Chinese Foreign Ministry spokesman Qin Gang.

According to Qin, the progress of the fourth meeting of the Working Mechanism for Consultation and Coordination on China-India Border Affairs will be released when it is concluded on Wednesday.

Qin told a regular press briefing the two countries had taken positive measures in maintaining peace and stability in recent years, and signed an agreement on border control cooperation.

"We are willing to make joint efforts with India to explore ways to maintain border peace and stability and strengthen coordination on border issues," Qin said.

China and India share a 2,000-km-long border that has never been formally delineated. The two countries began discussing border issues in the 1980s.

The two sides signed an agreement in New Delhi in January 2012 to formally launch the working mechanism. Under the agreement, the mechanism is headed by officials at the director general level from the Chinese Foreign Ministry and by officials at the joint secretary level from the Indian External Affairs Ministry, and is composed of diplomatic and military officials from both sides.
