No. You can't claim that treaty which targets the group of students who received their F1 visa originated from China. If you changed your status from F2 to F1, not having a F1 visa, you cannot claim that treaty. If you changed your status from F2 to F1, and got a F1 visa from a third country, such as Mexico, or Canada, you still cannot claim the treaty. Only if you went back to China and got a F1 visa, you can claim that treaty.
