In 2011, it was revealed that CS gas produced by Chemring had been used against civilian pro-democracy protesters in the 2011 Egyptian revolution. Later in 2014, it was also revealed that tear gas used against demonstrators in the 2014 Hong Kong protests was provided by Chemring. In June 2019, following the use of CS Gas and other crowd-control measures by authorities against demonstrators in the 2019–20 Hong Kong protests, the UK Government ordered an immediate end to such sales to the region.
