This brings into play all sorts of WRONG things about electrical codes - to include is the wiring up to standard and even capable of drawing that kind of amperage and or power.
IF you elect to simply replace the plug - it would be WISE to place a 16 amp circuit breaker inline - just in case you draw in excess of 16 amps...but really - have China Power come out, inspect the socket and the wiring all the way back to the circuit breaker - and pay the guy to install a 16amp socket for you.
That way - you may not melt the plug - but if your wiring won't handle it - you'll melt down the electrical wiring - potentially causing a short circuit or wire burn-out.
I checked the el-crappo wiring to the two lamps in our bathroom a few weeks ago - the copper core was no longer a copper color (it was some kind of silver/tin looking color) and one of the wires showed signs of burning (aka BLACK). I thought we were just having power control issues to the neighborhood when the lights would intermittently dim.
I also discovered the insulation had decayed and become brittle - creating perfect conditions for line breaks, short circuits, sparks, and electrical fires. Amidst much cussing - I replaced all the wiring from the central core (recognizable as solid copper cored wire) and used crimping connectors, which I then wrapped in electrical tape.
The electrical tape that was used looked more like some kind of cloth tape - but regardless of its insulation quality - it had also decayed into a hard brittle material that was a far cry from it's original flexible, pliable form - probably another electrical fire waiting to happen.
Long-story short - PAY the China Power technician to come out and replace the wall socket AND verify the wiring - maybe add in a separate circuit breaker for this socket (and label it yourself with permanent marker or a geeky label maker).
Finally - PRAY you get good luck and the tech is actually professional as opposed to some lazy glasshole gorilla pretending to be professional.
How to tell a professional from a gorilla - a professional will duct wire along the walls. A gorilla will string wire haphazardly along the ceiling.
Finally - a TRUE professional will clean up/police their mess (stripped wire casings, empty wrappers and boxes from any material they use, and they'll NEVER just twist two wires together and tape them up - they'll use either electrical connectors or splice boxes to splice wires together.
Finally, a TRUE professional won't smoke in your home and crush his cigarette butts on your floor (yes, I've seen and experienced lots of gorillas).
Enjoy - hope nothing catches fire during your tenure...
