Hong Kong Chief Executive Carrie Lam Cheng Yuet-ngor was supposed to attend the opening ceremony of the China Import and Export Fair and the Pearl River International Trade Forum in Guangzhou, as well as meet with Guangzhou leaders on Wednesday.

But the ceremony was postponed from Wednesday to Thursday, after typhoon Kompasu caused adverse weather in southern China and triggered the hoisting of storm signal No.8 in Hong Kong.

The Shenzhen leg of Lam's trip had to be canceled. The Hong Kong and Shenzhen governments will fix another date for their meeting.

On Thursday morning, Lam met with Guangzhou party secretary Zhang Shuofu, mayor Wen Guohui and other officials of the Guangzhou government.

She spoke to them about her policy address delivered last week, in particular policies for Hong Kong's integration into the national development.

Noting that Guangzhou and Hong Kong have respective strengths in such areas as finance and technology, the two cities can strengthen co-operation to complement each other, she said.

Seven Hong Kong universities have already, or are planning to set up campuses in Greater Bay cities. They will include the Hong Kong University of Science and Technology (Guangzhou) in Nansha, Guangzhou.

She thanked the Guangzhou government for its support for the project and said she is pleased that the school campus could be commissioned as soon as September next year.

She also spoke about the Hong Kong Science and Technology Parks Corporation and the Hong Kong University of Science and Technology, which had signed a co-operation agreement in August this year for a plan to establish an incubation base in Nansha, Guangzhou.

On financial development, Lam also said that the SAR government will back co-operation between the Hong Kong Exchanges and Clearing and the Guangzhou Futures Exchange in carbon emission trading.

Apart from Financial Secretary Paul Chan Mo-po, Lam and other Hong Kong officials concluded their visit to Guangzhou and returned to Hong Kong on Thursday afternoon.
