India says, despite the border dispute with China, relations between the two countries have been developing well. Government sources said, as there is no mutually-agreed boundary between the two countries, there is perception of incursions by both the sides. It said, even if the troops of the two countries come face to face at times, there are no hostilities and peace and tranquility are maintained on the border for the last three decades despite exchanges of protests and demarches. On settling of question over 3488 kilometer Sino-India boundary, the sources said the differences are extensive and cannot be resolved overnight.Meanwhile, India has not ruled out the possibility of a meeting between Prime Minister Manmohan Singh and his Chinese counterpart Wen Jiabao in Thailand on the sidelines of ASEAN Summit next week. The meeting would be significant as the two countries have been recently locked in recriminations over Arunachal Pradesh and other issues. AIR correspondent reports that notwithstanding the war of words, the two countries are proceeding with the setting up of a hotline between their Prime Ministers as per the decision reached in April as a confidence-building measure. The two countries will also have another high-level political contact when Chinese Foreign Minister Yang Jeichi visits New Delhi for Russia-India-China meeting on 26th of this month.
