Over the years, there has been more than a little symbolism to the disputes between China and India along the 5,000-kilometer border separating the world’s most populous countries.

In November, the two countries issued a statement to say they had reached an "important consensus" as they sought to step back from border tensions to promote trade and political ties. PWC forecasts that these two economies will be the largest on the planet by 2050, and so a great deal of attention is now focused on what happens next.
