BEIJING, Aug. 22 -- Chinese President Xi Jinping lauded the "outstanding contributions" of late leader Deng Xiaoping and urged advancing socialism with Chinese characteristics initiated by Deng, as the country marked Deng's 120th birth anniversary on Thursday.

Addressing a meeting held to mark the anniversary, Xi, also general secretary of the Communist Party of China (CPC) Central Committee and chairman of the Central Military Commission, said the country must continue to thoroughly study and apply Deng Xiaoping Theory.

"Deng made outstanding contributions to the Party, the people, the country, the nation and the world," Xi said, adding that Deng's achievements have been immortalized in history and will always inspire future generations.

Deng was the core of the second generation of the Party's central collective leadership, the chief architect of China's socialist reform, opening up and modernization, and the trailblazer of socialism with Chinese characteristics, Xi said, adding that Deng was also a great internationalist who made major contributions to world peace and development.

"Comrade Deng Xiaoping had lived a glorious, fighting and extraordinary life," he said.

Xi noted that, after the Cultural Revolution, a decade-long turmoil that ended in 1976, Deng had led the Party and the people in achieving China's historic transformation.

Deng pushed China to achieve a new breakthrough in adapting Marxism to the Chinese context, break new ground in socialist modernization, and set a correct path for the country's complete reunification, Xi said.

Deng's historical achievements are comprehensive and groundbreaking, with profound and lasting impacts on both China and the world, Xi said.

"We will forever remember his great historical achievements and forever revere his noble revolutionary conduct," Xi said.

The most important intellectual legacy left by Deng is Deng Xiaoping Theory, Xi said, calling for thoroughly studying and applying the theory to address real-world problems.

"The best way to honor Deng is to continue advancing the cause of socialism with Chinese characteristics that he initiated," Xi said.

Xi called for further comprehensively deepening reform to continuously provide strong momentum and institutional safeguards for Chinese modernization.

He urged moving faster to build a modernized economy, working toward greater self-reliance in the science and technology sector, and developing advanced socialist culture.

Xi also urged efforts to achieve more notable and substantive progress in promoting common prosperity for all.

Realizing China's complete reunification has long been the aspiration of Mao Zedong, Deng Xiaoping and other members of the older generation of revolutionaries, Xi said.

He urged resolute efforts to promote the peaceful development of relations across the Taiwan Strait, and demanded firm opposition to "Taiwan independence" to safeguard China's sovereignty and territorial integrity.

Stressing that China has always been a staunch force for world peace, Xi called for unremitting efforts to uphold peace, development, cooperation and mutual benefit.

Xi said China will take an active role in the reform and development of the global governance system, and create new opportunities for the world with new progress in Chinese modernization.

Senior leaders Zhao Leji, Wang Huning, Ding Xuexiang, Li Xi and Han Zheng attended the meeting, which was presided over by Cai Qi.

Zhao, Wang, Ding, Li and Cai are all members of the Standing Committee of the Political Bureau of the CPC Central Committee. Han is the country's vice president.
