BEIJING - China's annual sales of heavy-duty trucks in 2019 hit a fresh record of 1.17 million units, up 2 percent year-on-year, data from an auto industry data provider showed.

In December, around 90,000 heavy trucks were sold, up 9 percent year-on-year, exceeding industrial expectations, according to a report from cvworld.cn.

The sales rose for six consecutive months in the second half, while October witnessed a 14.1-percent growth, the highest in the whole year.

Intensified restrictions on older trucks and greater efforts of overload control were among the factors contributing to transformation in product structures and new purchases in the heavy-duty truck market, said the report.
