BEIJING - A long-delayed round of sensitive border talks between Chinese and Indian diplomats will take place in India from Sunday to Tuesday, the foreign ministry in Beijing said. Chinese State Councilor Dai Bingguo and Indian National Security Adviser Shiv Shankar Menon will attend the 15th meeting between special representatives on Sino-Indian border issues, the ministry said on its website. China and India share a 2,000-kilometre (1,200-mile) border which has never been formally delimited. The talks were cancelled in November after reports that Beijing objected to a scheduled speech in New Delhi.
