Coal machinery to see robust growth

China's coal machinery manufacturers are expected to continue their strong run till 2020, buoyed by a recovering coal mining sector, analysts said.

Wu Dongdong, an analyst with Hangzhou-based Zheshang Securities Co, said demand for coal machines increased as a majority of coal enterprises earned higher profits.

"As the effect of supply-side reform unfolded, coal prices started to rebound by the end of 2016, and coal companies' profitability improved significantly," Wu said. "Outdated machines in need of replacement are also driving demand in the coal machinery industry."
