Chinese GDP is expected to increase by more than 8 percent in 2013, a high-level adviser said on Wednesday.

Zheng Xinli, vice-chairman of the China Center for International Economic Exchanges, said according to the organization's estimation, Chinese GDP started to rise on the forth quarter of 2012 after 11 quarters' straight decline.

He made the remarks during the government think-tank's New Year reception in Beijing .

The Chinese economy achieved a soft landing last year, with average growth of 7.7 percent and CPI decreasing by 2.6 percent, he said.

This year will see bigger international and domestic markets in China, said Zheng, urging the related parties to take advantage of the opportunities and develop with the country.

"Chinese development means opportunities for both Chinese people and all those willing to conduct investment, trade and coo peration with China," he said.

Ambassadors and counselors from about 50 countries and representatives from international organizations joined the reception.
