Mr Wen, who is on a three-day visit to the UK, has already said he wants to welcome more UK products to China.

The two leaders are expected to sign an agreement to help UK companies work with China's regional cities, in architecture, civil engineering and research and development.

British poultry farmers are being allowed to export to China and the visit is expected to see agreements reached for the supply of pigs.

Chancellor George Osborne and Foreign Secretary William Hague are due to join Mr Cameron for the talks and Mr Wen is accompanied by other senior members of the Chinese government.

They are also likely to discuss improving cultural and educational relationships between China and the UK and global issues such as international security and climate change.

It follows Mr Wen's visit to Longbridge and to Stratford-Upon-Avon - the Chinese premier is a lifelong fan of William Shakespeare.
