On how far the relationship has succeeded in getting beyond the intractable border issue:
Attempts to improve military to military relations, even if symbolically, joint military exercises, CBMs, do make something of a difference. Economic diplomacy makes a difference, but the two countries don't really trust each other, it will take time to rebuild trust. China is also active in cultivating relations with other South Asian countries, apart from Pakistan--such Sri Lanka and Bangladesh. Indians are getting more active in South East Asia and with Japan. The two countries are involved in each other's backyards, are still feeling their way on how to build relationships. Neither wants confrontation, but the question is: how to build on areas of cooperation while recognising that the two sides are competitive?
