Zhang headed a team of 10 speakers from the Chongqing delegation who discussed their understanding of the insightful remarks in Hu's keynote speech to the congress, and how they will translate these words into action once the political report is endorsed at the end of the weeklong event.

They highly praised the theory of the Scientific Outlook on Development, the most important achievement of the Party in the past decade, and a theory that has become a guideline for the Party.

Zhang said people in Chongqing want to improve their standard of living. The gross domestic product of the municipality of 33 million people ranked 23rd among mainland provinces and regions in 2011, with the per capita income of its residents being lower than the national average.

"So scientific development is the priority of the government," he said.

Chongqing Mayor Huang Qifan admitted that the Bo and Wang Lijun cases stalled investment, and caused foreign and domestic investors to hesitate about putting their money into the municipality earlier in the year.

"The Party and the central government have taken timely steps, and since Zhang came in March, we have taken a series of measures ... for stable growth and stable investment," Huang said.

The number of private enterprises increased by 20 percent in the first nine months of the year, proving that the investment environment in Chongqing is improving, the mayor said.

Its imports and exports amounted to $40.4 billion in the same period, a surge of 120 percent, according to statistics provided by the municipal government.
