It is improvement but not innovation. Innovation is something never done before. For example, Su-57 has hybrid LERX / canards. That is innovation. For example, Su-75 has hybrid lateral / underside air intake. That is innovation. If Type 055 destroyer gets rid of main gun and replaces it with VLS then that would be innovation.MRNA in China can be stored for a week at room temperature, which is different from that in the United States.
