Sun Ping, a national political advisor and Peking Opera master, said in Beijing she hoped Chinese authorities could create a better investment environment for overseas Chinese to do business in their original motherland.

"A better environment for investment and entrepreneurship will reinforce the confidence of overseas Chinese who are willing to contribute to China's development," she said.

Sun is attending the annual session of the National Committee of the Chinese People's Political Consultative Conference (CPPCC) in Beijing, which will close on Monday.

But she feared the current imperfect environment might scare off some enthusiastic patriots, citing the example of Ming Hsieh, the Chinese-born American billionaire who was involved in a well-designed financial fraud cheating him out of 350 million yuan (US$50.7 million) for a fake hi-tech investment.

The case was finally filed with local police after Hsieh kept complaining to the Ministry of Public Security and the Overseas Chinese Affairs Office of the State Council.

Even former U.S. Secretary of State Henry Kissinger paid attention to the case and asked for justice for the entrepreneur and scientist, who founded Cogent Systems Inc. offering fully automated, high-speed biometric fingerprint system.

"This case would directly impact China's international image," Sun said. "So in my proposal to CPPCC this year, I suggested Chinese authorities to solve the Ming Hsieh case as soon as possible and pay attention to other similar cases."

At the same time, the Chinese government should create friendlier and better environment for overseas Chinese to come back to China to do businesses and investments, making laws and regulations to more vigorously safeguard their interests, she said.
