On Sunday 21 February central London will be transformed into a hive of Chinese arts and entertainment to welcome in the Year of the Tiger.
The official opening ceremony in Trafalgar Square will be followed by world-class dance, music and acrobatic performances, while cultural stalls and lion dance displays will line the streets of Chinatown.
Shaftesbury Avenue will become 'Hong Kong in London Chinatown', with a stage featuring performances by local Chinese artists.
The celebrations will culminate with a colourful fireworks display in Leicester Square.
Organised by the London Chinatown Chinese Association, London's Chinese New Year celebrations are the largest outside Asia.
"I am delighted to give my backing to London's Chinese New Year celebrations. Not only is it the largest outside Asia, it is undoubtedly one of the brightest, most colourful events to be seen in the capital.
"In 2010 it marks the start of the Year of the Tiger and we should take inspiration from some of the attributes of that fine creature. Looking forward to the end of the downturn, let's respond to future challenges with energy, assertiveness and courage," said Johnson.
