It would take some years until we properly see all the consequences, but I wouldn't be surprised if afterwards historians would note Covid-19 as a factor that benefited China in their long term competition w. "the west", not as a cost.
Like, 5k deaths is something that I wouldn't approve of for almost any reason, but looking back at documented 20th century history, planners (both in China and elsewhere) were clearly willing to pay such and even much higher costs for reasons of global politics/power play, so the mere existence of such a cost by itself certainly does not mean that it's implausible that someone would intentionally order a thing like that.
