Didi has let go of half of its 40 employees in the UK and shelved its expansion plans for overseas markets until at least 2025, The Guardian reported Wednesday, citing people familiar with the matter. The news marks the latest setback for the Chinese ride-hailing platform, which was put under investigation by Chinese regulators last July after its $4.4 billion US IPO, reportedly due to data security concerns. In April, the company revealed plans to halt its ride-hailing services in South Africa and shut down its food delivery business in Japan. [The Guardian]
