China will offer more shale gas blocks for exploration, the country's land watchdog said on Monday.

Although no timetable has been disclosed, Peng Qiming, director of the geological exploration department at the Ministry of Land and Resources, said the country will continue to open the shale gas market.

"We welcome all kinds of participants, such as private and joint ventures, to join in shale gas exploration," Peng said at a news conference on the results of the country's second shale gas tender.
