Chinese Premier Wen Jiabao agreed with his Indian counterpart on Saturday to work towards narrowing differences on long-simmering border issues between the two nations. Wen reached the agreement with Manmohan Singh on the sidelines of a regional summit in Thailand grouping the 10-member Association of Southeast Asian Nations (ASEAN) and other countries. Beijing had voiced opposition to a recent visit by Singh to Arunachal Pradesh, an Indian border state at the core of the dispute, and to a planned visit there next month by the Dalai Lama, the exiled Tibetan spiritual leader.Wen and Singh also agreed they would try to ensure peace and stability in the disputed border area, saying this would be conducive to resolving border issues and furthering bilateral cooperation.
