The impact of major economies' quantitative easing on China will be "marginal" and the nation should continue to deepen its ongoing financial reform, especially currency reform, to better cope with global economic uncertainty, said experts.

Fred Hu, chairman of Primavera Capital Group and a former economist at the International Monetary Fund, said based on the influence of US monetary easing in recent years, measures introduced by Japan and the United Kingdom would also have a very limited impact on China.

"We didn't witness a surge in capital inflows and devastating effects as some liquidity still goes back to the US. History has showed us that China's real problem and threat comes from its own economic mode instead of outside policy changes," he said.
