Japanese auto maker Toyota Motor (TM.NYSE, 7203.TYO) and retailer Aeon (8267.TYO) had resumed operations in China as of Sunday, following aggressive anti-Japanese protests, Bloomberg reported. Protestors burned Toyota storerooms and damaged vehicles, according to a company spokesman, during protests over Japan’s purchase of islands in the East China Sea that China also lays claims to. Aeon is currently assessing damage on one of its remaining two unopened stores. Honda (HMC.NYSE, 7267.TYO) reopened mainland factories but has yet to fully recover. A spokesman for Fast Retailing (9983.TYO), whose brands include Uniqlo clothing, said that on the company’s worst day during the protests, the “sales on that day were one third of what we would have gained.” Meanwhile, China has cancelled events to commemorate 40 years of diplomatic relations with Japan, The Guardian reported.
