A poll of more than 150 top executives at leading multinational companies by Boston Consulting Group found that China is still the most important market in their strategy over the next five years.

Richard Lesser, president and chief executive officer of BCG, said the gap between China and other emerging markets might even widen in the near future, because China's reforms are increasing confidence in its future, while other economies face uncertainties. For example, he said, in India there is even more uncertainty, and it's very complicated to do business.

"If the current leadership in India can step up and undertake the same kinds of reforms that the leadership here (in China) is talking about, we'll be very bullish about India, and I think companies will too," he said.

"Investors have been skittish since 2009, and any capital flow changes would make them nervous. But China's more insulated because it's a more internal financial system."

But on balance, he said, growth in developed economies also helps the entire world. The US, Japan and Europe being on a growth trajectory supports exports from other countries, which will also be a good thing.

"If the developed economies struggle, it will also put a damper here or there on emerging economies," he said.

Overall, QE tapering should not cause as much chaos as previous crises, experts said.

Li suggested that the process won't lead to another financial crisis similar to the one seen in 1997 to 1998 in Asia, because the world is better prepared with the guidance of the International Monetary Fund and the World Bank.

Zhu Min, deputy managing director of the IMF who was also present at he summit, agreed.

"The debt positions of emerging markets are in much better shape compared with 1998, and the strong net positions in terms of foreign exchange reserves are enough to withstand the crisis.

"If there is a short-term crisis in emerging economies, the IMF will surely lend a helping hand," he said, adding that emerging economies are still a major global growth engine.

Zhu also said that China shouldn't underestimate the external impact on its economy, as the country is now more correlated with the global economy, and opening its capital account may exacerbate this impact.
