He said that the US government should give fair treatment to Chinese businesses, including State-owned enterprises.

William Zarit, minister counselor for commercial affairs at the US embassy in Beijing, said that Chinese direct investment is vital to the US' economic growth, job creation and productivity.

"Recent notable Chinese investments reflect a very broad range of sectors, including shale gas, real estate, technology, food processing and the media," Zarit said.

He said that the US offers a good business environment, where intellectual property is protected and the predictable legal system resolves disputes quickly.

Also, as a result of free trade agreements the US has reached with many countries, Chinese products manufactured in the US can be exported duty-free to global markets.

"Energy costs in the US are among the least expensive in the world," said Zarit.

As for Chinese companies' concerns over investments blocked for national security reasons, Zarit said that most transactions that don't have any national security implications aren't being reviewed.

"Companies always encounter difficulties in fresh markets, especially since each of our 50 states has different tax structures, regulatory systems and even financial incentives for foreign investment," Zarit said.

He suggested that Chinese companies take advantage of the expertise provided by law firms, investment banks and public relation firms to improve their chances of success in the US.
