Chongqing's economic growth has rebounded after a slowdown earlier this year and is expected to continue leading the nation, a senior official from the southwestern municipality said.

Chongqing has led the nation in GDP growth, industrial value-added output, foreign investment and expenditure in the first half of this year, said Huang Qifan, mayor of Chongqing, at a conference in the city on Thursday.

"We were able to reverse the difficult situations earlier this year and maintained a good momentum of economic growth," Huang said.
