Production of large liquefied natural gas (LNG) trucks broke records in 2017 as China curbs diesel in its battle against air pollution.

A total of 96,000 LNG trucks were produced last year, a sharp contrast to 19,600 in 2016, according to an industry report released on Tuesday.

Sales of LNG trucks in 2017 were estimated at 80,000 to 85,000, said the report.
