Sony-Olympus deal held up by China

Why do Chinese regulators have the power to hold up this deal? Do both of these companies have interests in China?

Point to ponder: how/why China is involved?

Why the flack do chinese regulators have anything whatsoever to do with this???

The same Chinese regulators insisted Panasonic divest its interests in the battery JV with Toyota before approving the Sanyo takeover.

This is the worst case of poor reporting. Here is a journalist who reports that China is the culprit for the delay of a deal between Olympus and Sony without saying how China is involved in the matter. One gets the impression that China is the culprit of everything going wrong in Japan.
