- The train that links China directly to UK arrived in Yiwu
- The train was loaded with whisky, baby milk, medicines and machinery
- This is China's latest effort to strengthen trade with western Europe
The journey is the latest effort in China's drive to strengthen trade links with western Europe along a modern-day "Silk Road" route.
The world's top trading nation launched the "One Belt, One Road" strategy in 2013, and has since poured millions into constructing vast infrastructure links.
The train -- loaded with whisky, baby milk, pharmaceuticals and machinery -- departed London on April 10 and passed through France, Belgium, Germany, Poland, Belarus, Russia and Kazakhstan during its 20-day trip before arriving in Yiwu in eastern Zhejiang province, a major wholesale centre for small consumer goods.
London is the 15th city to be linked to a new freight network offered by the state-run China Railway Corporation, which says its services are cheaper than air transport and quicker than shipping.
The journey should be 30 days faster than moving the goods by ship, the provincial government had said, but the pilot run took two days more than the 18 days expected.
And the train, named the East Wind, has much less carrying capacity -- just 88 shipping containers, according to the Yiwu government, compared to the 10,000 to 20,000 containers cargo ships can carry.
It is unclear how much the venture cost, and some experts have questioned whether the ambitious project makes economic sense.
"It is hard to say at this stage what the economic return will be, as the economic benefits will come over a long time," He Tianjie of Oxford Economics Hong Kong told AFP.
China already has a regular direct freight train service to Germany, Europe's largest economy.
One route links the Chinese megacity of Chongqing to Duisburg, a steel-making town and one of Germany's most-important transportation and commercial hubs.
The other route links Beijing, the Chinese capital, to Hamburg, Germany's second-largest city.
Roughly 80 percent of global trade is shipped by sea as freight train services face technical and bureaucratic hurdles which vary according to country.
The East Wind's locomotive and carriages had to be changed en route because of the larger gauge on railways in the former Soviet Union.
Prime Minister Theresa May will visit China later this year, with talks likely to include closer trade ties for when Britain leaves the European Union, according to British officials.
