Uber confirmed that it has raised a further $1.2 billion in funding, led by search giant Baidu, in order to continue expanding Uber China, and the round is not yet closed. The news appears to have been timed to coincide with another big piece of funding in the Chinese transportation wars: Uber’s biggest competitor in the country, Didi Kuaidi, also confirmed today that it has raised an extra $3 billion for its own coffers.
