Chief Executive John Lee on Sunday said his administration will promote further cooperation between Hong Kong and the mainland city of Tianjin for win-win outcomes.

He delivered a speech via video link to a conference of entrepreneurs from the two cities.

The CE said Hong Kong is the biggest source of foreign investment for Tianjin, and the SAR’s super connector status, has enabled enterprises in Tianjin to establish their business overseas.

"Hong Kong brings together international capital and first-class financial talents, has abundant financing channels and a legal system that is in line with international standards," he said.

"The SAR government will continue to leverage Hong Kong's role as a 'super connector' and 'super value adder' to promote in-depth cooperation between Hong Kong and Tianjin for mutual benefit."

Lee also noted that the SAR administration and Tianjin signed a memorandum of understanding in April to promote aircraft leasing and financing industries, saying it brings opportunities and impetus to the aviation and financial industries in the two cities.
