Demand still exceeds supply at this moment. It's fine that middle income countries like Thailand are moving to expensive vaccine as poor countries cannot afford those (and the required cold chain). China should focus on vaccinating poorer countries.
China is doing a lot of studies on heterologous boosters to inactivated vaccines. Just sell inactivated vaccines with promises of booster shots in the future.
I am of the belief that China shouldn't attempt reopening until most vaccinated have received a booster shot. Remember the difference between 80% efficacy at preventing hospitalization and 90% efficacy at preventing hospitalization is huge. The later reduces hospitalization by half compared to the former. China just need more real-world data on boosters.
