The Coast Guard has rightly become concerned about what may be shipping in all those containers. We just had the Israeli intercept at sea, and now we hear that a couple of weeks ago, Malaysia seized two containers loaded with embargoed material that could be used to make WMDs including nuclear weapons bound from China to Iran.

There is no indication that the Chinese government was implicated in the transfer, but the US has been concerned that Chinese private companies may be helping the Iranians.
