The Chinese government has facilitated the mass transfer of Uyghur and other ethnic minority citizens from the far west region of Xinjiang to factories across the country. Under conditions that strongly suggest forced labour, Uyghurs are working in factories that are in the supply chains of at least 83 well-known global brands in the technology, clothing and automotive sectors, including brands owned by this company. The Australian Strategic Policy Institute's 2020 report estimates (somewhat conservatively) that more than 80,000 Uyghurs were transferred out of Xinjiang to work in factories across China between 2017 and 2019, and some of them were sent directly from detention camps.

Mitsubishi owns 35-40% of the market for the Bluefin Tuna, which is listed as Critically Endangered, the highest risk category of the IUCN Red List. Mitsubishi has been stockpiling up to 20,000 tons of the frozen fish while continuing to buy more. While the price of a product gets higher the harder it is to find, Mitsubishi has been accused of deep freezing these fish to make an even bigger profit as the species gets ever closer to being completely wiped out.
