China BioPharma Corp (fka CHBO)

You are right, they are. However, it's a question if they ever exercised their right to purchase a part of ZTPharma. Here's a part from 10QSB:
"On April 7, 2006, the Company entered into a Share Exchange Agreement for the purpose of acquiring 100% of the outstanding capital stock of China BioPharma Limited ("CBL"), a Cayman Islands company, which has rights to invest in Tianyuan Bio-Pharmaceuticals Company, Ltd"

We can only hope they did, and if they did...
