Subject: Iran jamming navigation in the Gulf
...and that's not going down well with China!

Half a dozen ships have diverted course on the way to the Strait of Hormuz, the crucial waterway connecting the energy-rich Persian Gulf to global markets since Sunday, according to shipping officials, analysts and marine-tracking data. Iranian lawmakers reportedly threatened its closure on Sunday.

Two Chinese-operated very large crude carriers went off course as they tried to enter the strait after their navigation systems were jammed as a result of military operations in Iran.

Whoops.
The problem with electronic jamming is that it's area-based and indiscriminate. They can't jam a US ship and not jam a Chinese ship at the same time.

About 50% of China's oil comes through...the Gulf. If Iran starts mining it or attacking transports ships, China is hurt the most.
