Entrepreneurs can always find ways to co-exist with stronger rivals in the international market through differential strategic development modes, said Shen Nanpeng, founder and managing partner of Sequoia Capital China.

He said the domestic energy market is dominated by State-owned players, but laws and regulations in foreign countries are beneficial for China's private companies to invest overseas.

China's largest overseas M&A so far - CNOOC Ltd's purchase of Canadian energy company Nexen Inc in 2012 - caused objections in Canada due to CNOOC's State-owned nature.

Some voices in Canada suggested that the country's oil and gas resources should not be developed by foreign State-owned companies.

However, Fung said Chinese energy and mining companies will continue to make big moves in foreign M&A markets, especially in natural gas.

"Timing is crucial for M&As," he said. "The global financial crisis and the European debt crisis will continue, which will bring chances for Chinese buyers."

Fung added that Chinese companies can explore some investment opportunities in US infrastructure construction projects.

"With established laws and regulations in the US, the risks are low for such investments," he said.
