Two entry Business visa issued in United States, but used for entry from India?

Hi,
I have a 2-entry business type valid until February 2014. I am flying from US to China next week (first entry). I will be working there for 3 weeks, fly to India for couple of weeks and re-enter China in first week of January (Second entry). Thus, for my second entry, though it was issued in the US, I am arriving in China from India.

So, for my second entry, does it matter that I am flying from India and not United States (where I got it essentially)?
Thanks a lot!
