MACAO, Dec. 20 (Xinhua) -- Chinese President Xi Jinping on Saturday urged unremitting efforts among central government officials and enterprise executives stationed in Macao to advance the cause of "one country, two systems."

Xi met with the officials and senior executives after attending the celebration marking the 15th anniversary of Macao's return to the motherland and the inauguration of the fourth-term government of the Macao Special Administrative Region (SAR).

Since Macao's return, the central government offices stationed in the SAR and the Macao branches of mainland enterprises and institutions have made significant contribution to local prosperity and stability, as well as the implementation of the "one country, two systems" policy and the SAR's Basic Law, said Xi.

The president urged them to keep working with firm belief to further boost the unity of the people from all walks of life in Macao.

They should have greater sense of responsibility and enhance working capability to push forward the practice of "one country, two systems" in Macao, on the basis of thorough understanding of the central government's policies on Hong Kong and Macao.
