BEIJING -- A Chinese government spokesperson on Monday hailed the general plan for building a Guangdong-Macao in-depth cooperation zone in Hengqin, saying it will inject strong impetus into the long-term development of the Macao Special Administrative Region (SAR).

The plan, made public on Sunday by the central government, is a significant measure to support Macao's appropriate economic diversification, and will facilitate the SAR's long-term prosperity and stability, according to the spokesperson with the Hong Kong and Macao Affairs Office of the State Council.

The spokesperson said the plan is of great importance and will have far-reaching consequences as it strengthens the ability of Macao to withstand external risks and challenges, and meets Macao compatriots' aspirations for a better life.

"One country, two systems" is the greatest strength for the development of Hong Kong and Macao, while China's reform and opening-up provides the biggest platform, the spokesperson said, adding that the release and implementation of the plan shows the determination of the central authorities to further deepen reform and advance opening-up.

"The great motherland will always stand firm behind Macao for its development," the spokesperson said.

The Macao SAR government and people from all walks of life are expected to understand and fully utilize related policies, seizing the important opportunities made available by the implementation of the plan, the spokesperson said.
