None of us have the same influence, pull, vote, or voice in China that we do no matter WHICH of the 50United States we are in.
China is a member of the United Nations and holds a permanent seat on the Security Council. The UN is centered in New York and it is just as easy for you to call NY or go to NY as it is to call or travel to DC.
It is true that you cannot elect anyone in China. However, it is also true that you cannot elect even a single Supreme Court justice. But you do, in fact, have the opportunity to try and outlaw abortion on a far wider, international basis. In fact, it could be argued that your individual influence with the UN is actually greater because they receive very little direct contact from individual citizens, while the federal government is drowning in tens of thousands of calls each day.
Your ability to influence China via the UN is only marginally less than your ability to influence the Supreme Court via the federal government with your 1 in 300 million vote.
The US Supreme Court justices are appointed by the very same president who also appoints our ambassadors, yet you never concern yourself with finding out who Alan Keyes would appoint to this position... even though the ambassador he appoints to the UN could help stop abortion in China and around the world.
You do, in fact, have an opportunity to fight abortion worldwide yet you make no attempt to do so. By your own standard this makes you pro abortion country by country and guilty of the same thing for which you condemn Ron Paul.
