"The annual flow of foreign direct investment was $1.6 trillion globally in 2011, while the ODI from China was merely $60 billion to $70 billion annually, so there is still a lot of room for improvement," he said.
Moreover, although China's investment flow ranked sixth globally, its foreign investment stock ranked only 13th, as the country has become a major global investor only in recent years, he added.
By the end of 2011, cumulative investments by Chinese enterprise in the US amounted to nearly $9 billion, against $20.3 billion in European countries.
But Chinese investors have already helped create more than 14,000 local jobs in the US, and employed 50,000 in European countries.
Overall, China's overseas companies paid $22 billion in taxes in 2011, while creating 890,000 jobs, among which 73 percent were local employees.
However, challenges are rising for Chinese investors overseas as they meet more restrictions from destination countries, not only in Europe and the US but also in traditionally friendly African countries, Chen said.
He suggested that China speed up work on an investment treaty with the US.
