BEIJING, Jan. 6 -- Chinese President Xi Jinping has stressed science and technology innovation to support productivity and national strength.

Xi made the remarks on Monday while meeting space scientists and engineers who participated in the research and development of the Chang'e-3 mission.

"Dare to walk the unwalked paths, constantly seek excellence through solving difficulties, and accelerate the shift to innovation-fueled development," Xi said, urging that science and technology innovation be put in a "core position" in the country's overall development.

The Chang'e-3 lunar probe, composed of a lander and China's first moon rover, named "Yutu," soft-landed on the moon on Dec. 14, making China the third country to carry out such a mission after the United States and the Soviet Union.

Yutu separated from the lander hours later and the two photographed each other on Dec. 15.

The Chang'e-3 mission marked the completion of the second phase of China's lunar program, which consists of orbiting, landing and returning to Earth.

On behalf of the Communist Party of China Central Committee, the State Council and the Central Military Commission, Xi congratulated the space scientists and engineers on the success of the lunar probe mission and extended his New Year's greetings.
