Huang Kunming, a member of the Political Bureau of the Communist Party of China Central Committee, encouraged Hong Kong enterprises to strengthen their confidence, seize opportunities and root themselves in the Guangdong-Hong Kong-Macao Greater Bay Area to actively invest in industries and technology.

Meanwhile, Hong Kong business representatives are expected to tell the stories of China, GBA as well as Guangdong to Hong Kong compatriots and international friends to help attract more foreign people to visit, invest and start their businesses in GBA, said Huang, also Party secretary of Guangdong province.

"The Guangdong provincial government will continue to spare no effort to support the development of Hong Kong enterprises in Guangdong, vigorously promote the construction of a first-class business environment and strive to build a sound market, industry, enterprise and service system, allowing investors to come and develop their business with peace of mind," he said.

Huang made the remarks at the Guangdong-Hong Kong Deepening Economic Trade and Investment Cooperation Conference held in Guangdong's provincial capital on Monday.

John Lee Ka-chiu, chief executive of the Hong Kong Special Administrative Region, said the business community of Guangdong and Hong Kong has, for decades, been a participant, beneficiary, and contributor to economic, trade and investment cooperation between the two regions.

He said Hong Kong would continue to join hands with Guangdong province to help build GBA into an international first-class bay area and world-class city clusters and promote the formation of more effective economic and trade cooperation results.

Companies from Guangdong and Hong Kong signed a total of 126 economic and trade cooperation projects valued at more than 100 billion yuan ($14 billion) at the event. These projects mainly involved commerce, investment, financial cooperation, modern logistics, innovative science and technology, green development, low-altitude economy, culture, tourism and sports.
