Macau's chief executive-elect Sam Hou-fai has pledged to work with Hong Kong in leveraging the advantages of the two SARs to foster development.

"On whether we and Hong Kong could complement each other's strengths and foster mutual development, I think there's huge potential in this," Sam said in a press conference on Sunday flanked by his incoming cabinet.

He said he will meet with Chief Executive John Lee after he assumes office on December 20.

"After I take office, I'll talk to Chief Executive John Lee about how the two SARs can – on each side of the Pearl River and under our common constitutional and political system – fully leverage our respective advantages to foster development.

"We'll also look at how we can leverage our strengths and seek opportunities, while integrating into the nation's development, as we strive for achievements for both SARs."

Sam and his governing team met the media a day after Beijing approved his nominations and appointed principal officials for the new term of the Macau government.

"The formation of this government's principal officials and prosecutor-general embodies the spirit of 'upholding fundamental principles and breaking new ground', which completely aligns with the requirements I set out for principal officials," he said.

The incoming Macau leader added his government will respond to issues the public is most concerned about, and work on key tasks relating to the city's long-term development.
