That seems to be the case since an article discussing leading vaccine candidates around the world failed to mention two Chinese candidates that are already in Phase III testing. One of the vaccines, developed by the company Sinovac, is beginning testing in Bangladesh and Brazil. The other vaccine was developed by Sinopharm, and is about to begin stage three testing in Abu Dhabi.
It is difficult to understand how an article focused on leading vaccine candidates would exclude two of the vaccines that are furthest advanced in the testing process.
