Chinese President Xi Jinping on Monday called "one country, two systems" the best institutional arrangement for Hong Kong's prosperity and stability.

Xi, general secretary of the Communist Party of China Central Committee, visited an exhibition at the National Museum in Beijing profiling the achievements made in Hong Kong since its return to the motherland in 1997.

At 3:00 p.m. Monday, Xi and other senior leaders arrived at the National Museum, accompanied by Leung Chun-ying, chief executive of Hong Kong Special Administrative Region (HKSAR).

During the last 20 years, "one country, two systems" has proven not only to be the best solution to the Hong Kong question left over from history, but the best institutional arrangement for Hong Kong's long-term prosperity and stability since its return, Xi said.

"We will continue to comprehensively and precisely implement the 'one country, two systems' principle, handle affairs in line with the Constitution and the Basic Law of the HKSAR, and further promote the overall development of Hong Kong," Xi said.

Xi said he hopes Hong Kong compatriots would join with all people of the country to advance "one country, two systems" in Hong Kong, and strive to maintain the region's prosperity and stability, creating a more beautiful tomorrow.

Other senior leaders Li Keqiang, Zhang Dejiang, Yu Zhengsheng, Liu Yunshan, Wang Qishan and Zhang Gaoli also visited the exhibition.

When Xi entered the exhibition hall and pressed a button on an interactive display, a beating heart glowed on a big screen.

The display, named "concentric circles," showed that Hong Kong compatriots and all other Chinese people are of one heart and contribute together to the nation's development.

The exhibition, organized by the HKSAR government, has 10 display areas. Photographs, graphics and interactive multimedia showing Hong Kong's development, opportunities and engagement with other Chinese cities held the attention of the leaders.
