It's just one letter, dammit

The headline for the Slate version of the story was intriguing: Nimitz Dicks in Hong Kong Despite Tense U.S.-Sino Relations

As expected, the headline in the BBC version was less so: Nimitz docks in Hong Kong despite China tensions
Odd, that 'China tensions' became 'tense US-Sino relations', ain't it?
Oh, yeah, and that the aircraft carrier (though, doubtless, not its crew) did not dick Hong Kong...
