Industrial output dropped 10.1% in 2020 from a year earlier, to the lowest level in at least seven years, as the novel coronavirus pandemic hit the nation's transport and machinery sectors, government data showed Friday.

The seasonally adjusted index of output at factories and mines stood at 90.9 against the 2015 base of 100, for the lowest reading since comparable data became available in January 2013, the Economy, Trade and Industry Ministry wrote in a preliminary report.

Production fell sharply in the spring of 2020 after the expansion of the COVID-19 pandemic disrupted supply chains, constrained socioeconomic activities and reduced consumer demand.
