Honolulu, Hawaii: China will put green industry as the key sector to absorb foreign investment, President Hu Jintao said Saturday on the APEC CEO summit.

According to Hu, the total output of the Chinese environmental industry is expected to reach 2 trillion yuan ($315.4 billion) by 2015, and investment to the industry during 2011 and 2015 is to reach 3.1 trillion yuan ($488.9 billion).

"The strong green demand and China's sound investment environment will provide a vast market and great investment opportunities to businesses in all countries, those in our region in particular," Hu told a cluster of more than 1,000 heavyweight businessmen at the annual APEC CEO summit.

President Hu arrived in Hawaii on Thursday to attend the 19th leaders meeting of the Asia Pacific Economic Cooperation group.
