"David Cameron Secures £45m Pig Semen Deal Between UK and China"

I'm sure there's a hilarious punchline here somewhere, from The Evening Standard (4 December 2013):
David Cameron secured an agreement for the UK to supply exports of the semen to Chinese breeders during his three day trade visit to China.
It follows industry lobbying in the Far Eastern country after a deal for the export of live pigs between the countries was signed last year.
In the new year, four artificial insemination centres in England and Northern Ireland, which are operated by some of the world's biggest pig breeding companies will begin exporting frozen and fresh semen.
I dunno, something like: "I wonder if Cameron diluted it with some of his own. The filthy bastard.", or "Perhaps he sweetened the deal by offering them some nearly-new pigs' heads as well."
