China has such low rates of new infections that clinical trials have to be performed elsewhere in the world. That's a great "problem" to have because you largely controlled the pandemic in your borders so phase 1,2,3 has to be done outside China.
Whereas US can do local trials and enroll local patients quickly and have sufficient COVID cases due to surging infection rates and conclude clinical trials faster, and get FDA authorization much quicker.
The US can feel better they are first to market, but they are the number #1 corona hotspot, so they actually need it. China is making above average progress with a largely controlled pandemic, which is in a envious position in grand scheme of things.
Leave it to the Westerners trying to spin a positive to a negative given China's unique circumstances of controlled pandemic and less urgency to mass vaccinate like hotspots US/UK.
