Leaders from both countries said the project is an important milestone to increase trade between Europe and Asia.
The train took 18 days to cover the 12,000 kilometre intercontinental journey passing through Kazakhstan, Russia, Belarus, Poland, Germany, Belgium and France before entering Britain through the Channel Tunnel.
Cargo in the 24 containers included clothing and other retail goods.
The train left on January 1 from the industrial city of Jiwu.
China, the world's top trading nation, in 2013 announced a new Silk Route to strengthen trade ties throughout Asia, Russia and Europe.
