While British Petroleum fights to pin blame on others for the 2010 Gulf of Mexico oil disaster, they somehow have convinced one of its Japanese business partners to pay for part of it.

MOEX, a unit of Japanese trading firm Mitsui and Company, will pay just over $1 billion to cover damages and clean up.  MOEX is a 10% shareholder of BP.

British Petroleum is struggling to come up with an estimated $40 billion to pay for damages and clean up.
