IMHO - having travelled to China from the west coast many times - and myself being 3 weeks since surgery, I wouldn't go that soon.
You're not going to be anywhere near 100%, what food you can east will still be an issue, you're probably going to have issues with gas, swallowing, etc. for a while. Everyone heals differently but 2 weeks is really pushing things.
Aside from the aforementioned you may need different RX's and medical care depending upon your situation. In my case I was off of pain meds within the 1st week and only needed meds for nausea once but lots of people do have to keep taking these meds for a while.
Assuming you've been to China and the areas you're going to visit before then you probably know how to get medical care while there....if not then you should find out in advance just in case you need a doctor/hospital.
