The Chinese companies include major real estate firms such as ABP (China) Holding Group, which is developing the 1-billion-pound ($1.68-billion)Royal Albert Dock project, and Dalian Wanda Group Corp Ltd, one of China's largest and most ambitious conglomerates.

Dalian Wanda closed two deals in June last year, investing 700 million pounds to build a five-star hotel by the River Thames and buying a 92-percent share of Sunseeker Yachts for 320 million pounds.

"We are extremely excited to be operating in London," says Lizhou Zhang, general manager of Dalian Wanda UK.

"The city is one of the main business and financial hubs in the world, and it is the perfect place for us to be in order to develop our major new project, all the while reaching new markets and helping us to achieve our international ambitions," he says

Cao says: "As the number of Chinese companies going global continues to rise, London appears to be well and truly open to Chinese investment. London provides the best financial and professional services, which makes it easier for them to grow and expand their businesses, even branch out into other markets like Europe, Africa and the Middle East."

London has many outstanding attributes that are recognized worldwide, Innes says, including "a deep pool of talent, superb access to markets and financial backing, and a well-earned reputation for innovation and creativity". Investment by the new Chinese companies will create 1,138 new jobs after they have been in London for three years, London & Partners says.

Innes says he is proud that London & Partners has been able to showcase its strengths to China, not only helping many Chinese companies to come to the city and develop there but also creating new jobs and economic growth that will benefit not only London but the country.
