ON an official visit to Britain from July 9 to 11, Shanghai Mayor Ying Yong met his London counterpart, Sadiq Khan. He said the two sister cities have cooperated well in all fields since establishing close ties in 2009.

“The sustained, good relationship between our two countries laid a sound foundation for Shanghai and London to deepen cooperation,” Ying said, adding that the Shanghai Pilot Free Trade Zone is the springboard for Chinese investors to go abroad in the Belt and Road Initiative. Shanghai and London can help companies to grow business.

As two mega cities in the world, Shanghai and London should share experiences and learn from each other to tackle common problems in urban development, housing, public transport, employment and environmental protection.
