Chinese Premier Wen Jiabao expounded on "The Scientific Outlook on Development" for Bruce Alberts, editor-in-chief of the Science Magazine of the United States on Sept. 30.

In the two-hour exclusive interview at the Zhongnanhai leadership compound, Wen said the first and foremost principle of the concept of scientific development is to put people first, to make every person attain full and harmonious development in an equal and free environment.

He said the comprehensive development came to the second, which means the integration of economic development with social development, the integration of economic reform with political reform, the integration of an opening-up and inclusive approach with independent innovation, and the integration of advanced civilization with traditional Chinese culture.

"Thirdly, we need to resolve the disparities, including rich-poor disparity, regional disparity and urban-rural disparity in our country's developmental process. " He added.

Sustainable development is also an important part of the concept, which aims at meeting the challenges of population, resources, and environmental protection faced by the 1.3 billion Chinese people in the modernization process. He said.

"We want to achieve sustainable development by adopting a resource-conserving and environment-friendly approach."

He also emphasized that these four goals could not be achieved without science and technology or without innovations.
