A roundtable aimed at strengthening ties between Beijing's Xicheng district and the City of London was held in the UK capital on Tuesday. Both areas share a heritage of being the historical centers of their respective capitals and are renowned for their financial sectors.

Beijing and London have maintained a formal friendship for more than two decades, with Xicheng district establishing ties with what was then the UK's department of Trade & Investment in 2011.

Liu Dongwei, Communist Party chief of Xicheng, said he expects the district to continue to collaborate with the City of London to enhance the financial sector, digital economy and asset management.

"Xicheng is a vibrant financial and wealth hub in China," Liu said.

"Beijing Financial Street in the district is home to China's financial regulatory authorities and major financial institutions from both domestic and international markets. We warmly welcome more investors to join us in opening a new chapter for both areas."

To date, Xicheng has attracted 280 fintech and professional service enterprises with registered capital of up to 140 billion yuan ($20.5 billion), with the intention being a continued focus on growth and innovation.
