The WSJ’s China blog interviewed an Indian economist who wrote a book saying China will become the leading power in fairly short order following the “China 2030″ report.

The interview mostly rehashes the regular Chinese storylines but the economist also makes some good points about how it’s in China’s self-interest to ensure stability and growth in Europe and the rest of the world.

The Chinese could build a much bigger IMF by lending it, say, $300 billion, which could be matched by Japan and emerging markets. If you get the IMF up to $1 trillion to $1.5 trillion in resources, that becomes an insurance policy for China.
