BEIJING, Oct. 16 (Xinhua) - It is the solemn historic responsibility of today's Chinese Communists to continue opening new chapters in adapting Marxism to the Chinese context and the needs of the times, Xi Jinping said on Sunday.

"Our experience has taught us that, at the fundamental level, we owe the success of our Party and socialism with Chinese characteristics to the fact that Marxism works, particularly when it is adapted to the Chinese context and the needs of our times," said Xi at the opening session of the 20th National Congress of the Communist Party of China (CPC).

"Marxism is the fundamental guiding ideology upon which our Party and our country are founded and thrive," he said.

Since the 18th CPC National Congress, with the courage to make theoretical explorations and innovations, the CPC has, from an entirely new perspective, deepened its understanding of the laws that underlie governance by a communist party, the development of socialism, and the evolution of human society, he said.

"It has achieved major theoretical innovations, which are encapsulated in the Thought on Socialism with Chinese Characteristics for a New Era," Xi said.

"The main elements of this theory are summarized in the 10 affirmations, the 14 commitments, and the 13 areas of achievement that were articulated at the 19th CPC National Congress and the Sixth Plenary Session of the 19th Party Central Committee, all of which we must adhere to over the long term and continue to enrich and develop," he said.
