China and India are trying to write a new page of the world economy
  • The Sino-Indian summit last week could be a new departure for neighbors who realize there is no alternative to constructive political, economic and security engagement.

  • China and India are part of a Eurasian institution that can make that possible.

  • Those two countries could soon become the key drivers of global demand and output.

Trust is an economic variable sounded like an echo swirling around Wuhan's East Lake in China as President Xi Jinping was hosting last Friday and Saturday Indian Prime Minister Narendra Modi for an "informal," "heart-to-heart" summit.

References to the two countries' cultures and civilizations, and metaphors about the sacred Yangtze and Ganges rivers, were abundantly used to underscore the importance of trust and mutual understanding for the strategic partnership of Asian neighbors who account for 35 percent of humanity and a quarter of the world economy.

That exalted talk may have been the proper mood music for the occasion, but an economic technician could have thought how simple and easy it would be for the two countries to solve one of their key bilateral issues. For example, India relatively small $40 billion savings-investment gap could be easily closed by China's $165 billion of excess savings looking for foreign portfolio and direct investments.

Simple? Not quite. Investments are an act of faith and a leap into unknown where trust acts as a sort of ultima ratio in risk-adjusted profit assessments.

Opt for a 'win-win' deal

And risks are plentiful along an unresolved Sino-Indian land border that stretches more than 2,000 miles. There is also a China-financed $50 billion Pakistan economic corridor passing through the contested part of Kashmir. Beijing is viewed with suspicion for its intrusions into India's traditional spheres of influence (Sri Lanka, Bangladesh, Nepal and the Maldives), while China apparently believes India is a geopolitical swing state.

Those were some of the key topics Xi and Modi discussed last week in an attempt to establish a stable and predictable bilateral relationship that would support a world order based on globalization, multilateralism and peaceful coexistence.

That was all very similar to what Chinese Paramount Leader Deng Xiaoping and Indian Prime Minister Rajiv Gandhi talked about 30 years ago as they sought to mend ties following a short border war China and India fought in 1962. It was on that chilly morning in December 1988 that Deng, in a long handshake, greeted his guest "I welcome you to China, my young friend," and a prophecy that "the Century of Asia will not come without the development of China and India."
