Two more questions were addressed: one apparently successfully, the other without immediate resolution. The riparian question was cordially dealt with, with the assuaging of India's apprehensions about damming of rivers upstream seeming to have begun with an agreement on greater sharing of hydrological data. It has appeared for a while that mutual misapprehensions have been more a question of transparency rather than an issue of substantive disagreement.

The one that got away was the issue of India's adverse balance of trade with China - $29 billion in 2012 according to Indian media reports. Indian media also reported that the economic delegation accompanying Li consisted preponderantly of business representatives who were interested in a greater share of the Indian consumer market rather than being "buyers" of raw materials and finished goods. That is a problem that has to be addressed by the ministries concerned in further negotiations, keeping in mind, of course, the relevant size and structure of the respective economies. It can hardly be wished away, for instance, that China has a far more robust manufacturing sector producing cheaper goods bought all over the world, not just in India.

But in a sense these are matters of detail. There are two important points that need constant iteration. One is a matter of principle as well as pragmatism. India has an unsettled border already with Pakistan, which needs constant policing. One wishes that Indo-Pakistani relations improve to the point that this no longer remains the case, but no one is realistically holding his or her breath until that happens. The border with Nepal, too, is problematic for a variety of reasons, the least of which not being the attempts of some countries to use it as a launching pad for incursions of various kinds.

The Indo-Bangladeshi border is the most "secure" but remains a concern over smuggling, infiltration by various groups, though now much reduced, the problem of enclaves and, finally, problems caused by rivers that keep shifting courses creating a huge problem of erosion and shifting borders.

In such a situation, pragmatism surely demands foregoing the luxury of opening up another front, especially when it has been abundantly demonstrated at least over the past quarter of a century that Sino-Indian disagreements can be amicably resolved.

The matter of principle is no less important. First, of course, is the blindingly obvious and, therefore, somewhat vacuous, point that negotiation is always better than hostile posturing. The more important point is that as two of the biggest economies in the world, more specifically in Asia and the global South generally, India and China have common interests - not least of which is to provide leadership to the developing world in the crucial areas of global negotiations on environmental and trade-related issues.

This can hardly be dismissed as the pipedream of a bleeding-heart, left-liberal intellectual forever positioning himself - in this case - against the neo-imperialist designs of, specifically, the United States. In fact, the past decade or more has shown clearly that when India, China and the other emerging economies have made common cause, the unfair, self-aggrandizing and at times almost criminal self-interestedness of the developed world has been successfully countered.

That has much, much more value than petty minded bickering over trivial details.
