Hong Kong wants its companies to partner with British counterparts so they can take on projects together, both in China and other economies in the area covered by the Belt and Road Initiative, attendees of a conference in London heard on Thursday.

Carrie Lam Cheng Yuet-ngor, chief executive of the Hong Kong Special Administrative Region, spoke about opportunities to strengthen business ties with the United Kingdom at the event attended by more than 1,000 business and government representatives.

"As Asia continues to drive the global economy's growth, we welcome British companies interested in exploring new business opportunities in the East, to explore opportunities in Hong Kong, to partner for success in the East," said Lam.

Think Asia, Think Hong Kong was hosted by the Hong Kong Trade Development Council and covered topics including partnership opportunities, financial technology, and the technology and innovation sectors.

The UK is now the SAR's second-largest trading partner in Europe, with investment worth 25 billion pounds ($34 billion) at the end of 2015, a 115 percent increase on five years earlier.

Greg Hands, the UK's minister of state for trade and investment, noted the importance of Hong Kong as a "key junction" for British companies' engagement.

"The UK must harness our shared ties (with Hong Kong), so that our firms, from infrastructure to energy, can become partners of choice in this initiative. As global trade moves toward emerging economies, the UK will seek to open up trade with willing partners in the region, and the free trade will bring us benefits," Hands said.

Margaret Fong, executive director of the Hong Kong Trade Development Council, said Hong Kong wants to facilitate connections between British and Chinese companies.

The Belt and Road Initiative seeks to boost trade and investment ties between Asia and Europe by strengthening infrastructure connectivity.

Earlier this month, the Hong Kong Trade and Development Council hosted a Belt and Road summit attended by more than 3,000 participants, including representatives from 170 infrastructure projects.

One day before the conference, the Hong Kong SAR and the UK government signed a strategic agreement to explore collaboration. They also signed a separate agreement to strengthen financial technology cooperation.

Francis Law, president of the Hong Kong Mediation Center, welcomed the financial technology collaboration.

"It will further enhance the growth of Hong Kong investment in the UK and attract firms to establish in Hong Kong and the Chinese mainland," Law said.

The UK government will also support a festival to showcase the best of the UK's innovation and creative sector companies.
