Conditions in China's construction machinery industry this year will continue to be tough and complicated after a dramatic drop in the past year caused by the economic slowdown, according to senior officials and business leaders.

Sales in the industry will see 13 percent growth this year compared with last year, provided the government meets its target of keeping GDP growth at 7.5 percent, said Su Zimeng, secretary-general of the China Construction Machinery Association.

Su was speaking in Munich during Bauma 2013, the 30th International Trade Fair for Construction Machinery, Building Material Machines and Mining Machines.
