The Bangladesh government called on China for help in repatriating Rohingya refugees to Myanmar during a visit by Foreign Minister Wang Yi, who promised better trade ties, investment and support for infrastructure development in the South Asian nation, AP reports.

Wang arrived in Dhaka on Saturday and met with Prime Minister Sheikh Hasina and Foreign Minister A.K. Abdul Momen. They discussed bilateral and global issues before his departure Sunday, said Shahriar Alam, Bangladesh’s junior minister for foreign affairs.

The junior minister said China pledged to work continuously to resolve the Rohingya crisis and quoted Wang as saying that Myanmar’s internal challenges were troubling other countries, AP reports.

“Our foreign minister strongly reiterated that Chinese cooperation is needed. China has progressed on resolving the Rohingya issue and we need the situation to come to an end,” Alam said.

China has been involved in the Rohingya issue before. In November 2017 is worked out a deal with Myanmar for the return of about 700,000 Rohingya to Myanmar. However, the refugees feared to return.
