Chief Executive John Lee on Monday said his administration has been focusing its attention on economic development and that business is a "win-win" situation for all, as he met with Lao officials as part of his third trip to Asean countries.

Lee is leading a delegation to Laos, the first stop of a six-day visit to three nations that also includes Cambodia and Vietnam.

Lee met Laos' deputy prime minister and foreign minister Saleumxay Kommasith, witnessing the signing of a number of memoranda of understanding between the two places.

"We think that business is always a win-win situation for the people of both places, and I have been focusing the whole government and society's energy and attention on strengthening economic development and business," Lee said during the meeting.

"The purpose of my visit to Laos on this occasion is, first of all, to strengthen ties between government and government, and of course, strengthen ties between business and business, and also very importantly, strengthen ties between people and people."

Kommasith, for his part, pointed to a new action plan signed by President Xi Jinping and General-Secretary of the Lao People's Revolutionary Party Thongloun Sisoulith last year, saying it will be a solid foundation for bilateral cooperation.

Kommasith also said the country is committed to working with the SAR.

"It's a good opportunity for me and the [Lao People's Democratic Republic], both the government as well as the business community, to discuss and find a way to further expand economic trade cooperation in the [Lao People's Democratic Republic] and Hong Kong," he said.

Lee also met Laotian Prime Minister Sonexay Siphandone, who welcomed the SAR delegation and called the visit a milestone on economic, cultural, trade and investment cooperation.

On social media, the chief executive thanked Laos for supporting Hong Kong's bid for accession to the Regional Comprehensive Economic Partnership.

"I believe that the volume of trade and investment flows between Laos and Hong Kong have ample room to grow. We see much prospect for deeper collaboration of our economic relations as both economies place importance to the developments of green economy and digital economy," Lee wrote.
