Chinese and European senior officials urged further cooperation through the Sino-Euro railway on Wednesday.

The 11,179-km Chongqing-Xinjiang-Europe railway connects Chongqing with Duisburg, Germany, via Kazakhstan, Russia, Belarus and Poland.

"I hope the Sino-Euro railway can extend to all 16 Central and Eastern European countries," said Huang Qifan, mayor of Southwest China's Chongqing municipality, at the Local Leaders' Meeting of China-Central and Eastern European Countries in Chongqing on Wednesday.
