Of course, there remain irritants in bilateral relations, with the most significant being the border dispute, China's increasing influence in South Asia and the skewed balance of trade.

But that the current Indian government is serious about its relationship with China has been demonstrated by External Affairs Minister Sushma Swaraj's just concluded visit to China and the announcement of Modi's visit in May 2015.

Also, during his visit to India in September 2014, Xi and Modi discussed all the important issues, including territorial and water disputes, and the Chinese president promised an investment of $20 billion in India over a period of five years.

What the naysayers in both countries need to realize is that in a changing world and with its growing economic clout, India cannot remain a non-aligned or be excessively dependent on any one country. It is for this reason that India has been following a policy of "multi-alignment" over the past two decades. This does not imply any compromise with its core strategic and economic interests, rather it means keeping national interests at the forefront. Modi seems to be following this policy by emphasizing that New Delhi is open to engagement with all countries.

So while India and the US may converge on economic and strategic issues, China and India can be on the same page on other issues vis-à-vis the West, which among other things include climate change. The increasing economic and strategic clout of the two countries also means that after the withdrawal of US combat forces from Afghanistan, they need to jointly fight terrorism and find areas of cooperation to help the battle-ravaged country's economic reconstruction.

Relations between China and India have numerous layers yet one thing is for certain that they are likely to be dictated by realism and rationality rather than idealism and emotion.
