If the 1993, 1996, 2005 and 2012 border agreements have been unable to check Chinese aggressiveness, how can a fifth one succeed? asks Claude Arpi.
The Fifth India-China Strategic Dialogue was held in Delhi earlier this year. While some progress is said to have been made in narrowing the ever-growing trade (im)balance in favour of China, Beijing remained stuck on its position on the border issue as well as on a possible collaboration on the Brahmaputra and other trans-border rivers.
After the meeting, it was reported that 'both sides put their faith in the most recent bilateral mechanism, the [2012] Working Mechanism on Border.'
Well, this has not stopped the Chinese from intruding into India's territory.
Foreign Secretary Sujatha Singh and her Chinese counterpart Vice Foreign Minister Liu Zhenmin (who served many years as Director-General, Department of Treaty and Law in China's ministry of foreign affairs) wanted to finalise a fresh Border Defence Cooperation Agreement, BDCA.
At a time the Chinese regularly try to create trouble on the Line of Actual Control, can a new agreement be more efficient than the previous ones of 1993, 1996, 2005 and 2012?.
