The Chinese government declared martial law on 20 May and mobilized at least 30 divisions from five of the country's seven military regions. At least 14 of PLA's 24 army corps contributed troops. As many as 250,000 troops were eventually sent to the capital, some arriving by air and others by rail.

At the 1989 FA Cup Final between Liverpool and local rivals Everton, held just five weeks after the Hillsborough disaster, the players from both participating teams wore black armbands as a gesture of respect to the victims.
