Macau has made huge development accomplishments, the economy has sustainable growth, people's livelihoods have significant improvements and society is accommodating and harmonious These achievements, he said, were thanks to the Basic Law and the principle of "one country, two systems". "I believe that the Macau Special Administration Region chief executive and the government will continue to lead different sectors of the community to govern and construct Macau well, keep making new accomplishments and create new magnificence," Wu said. Earlier in the day, Wu met Macau Chief Executive Fernando Chui Sai-on. During their discussion, Wu urged Macau to put the emphasis on long-term development. He said Beijing backed the administration and other sectors to strive hard, and stay united. He said the return of Macau to Chinese rule for 13 years had proved that the principle of "one country, two systems" had "strong vitality". Wu said he would like to learn more about Macau's development, history and culture during his three-day visit. Wu, along with other top officials, will attend a ceremony commemorating the Basic Law this morning, before visiting the Macau Chamber of Commerce. The Basic Law in Macau was promulgated on March 31, 1993, and took effect on December 20, 1999, when the city was handed over to mainland China.
