Hong Kong has a wide network of global connections that can support provinces in the pan-Pearl River Delta across southern China link up with the rest of the world, Chief Executive Leung Chun-ying says.
"Hong Kong has extensive international connections and acts as a channel for capital, talent and technology," he wrote in an article  sent to media yesterday. "It will continue to contribute substantially to the further development of the [pan-Pearl River Delta] provinces, which would in turn create career development and business opportunities for Hong Kong people and enterprises in various sectors."
The grouping comprises the special administrative regions of Hong Kong and Macau plus the provinces of Guangdong, Fujian, Hainan, Guizhou, Yunnan, Sichuan, Hunan, Jiangxi and Guangxi.
Leung contributed the article after attending the two-day Pan-Pearl River Delta Regional Co-operation and Development Forum in Hainan.
He writes that mainland companies that intend to expand overseas can seek professional advice from the more than 70 foreign law firms in Hong Kong, which have the advantage of being conversant with the laws of their respective countries.
He said only by achieving relatively high and sustainable economic growth could the government solve the city's problems.
Leung also said he had explored the areas for closer co-operation with the provinces's leaders, including promotion of multi-destination itinerariesin Hainan, help export its products to the international market in Yunnan, serve as an intermediary to help Guangxi attract more investment, further enhance exchange and co-operation with Sichuan, and explore the feasibility of extending the pilot implementation of measures under the Economic Co-operation Framework Agreement and the Mainland and Hong Kong Closer Economic Partnership Arrangement with Fujian.
