The article pretty much answers this:
China has issued 100 billion yuan (about 14.1 billion U.S. dollars) of special government bonds for COVID-19 control measures in a bid to support local infrastructure construction and epidemic prevention and control, the senior official added.
It is set to counter the downward pressure on economic growth, expand tax and fee reduction policies to help enterprises tide over hard times, and strengthen budget balance to mitigate the adverse impact of the epidemic on fiscal revenue growth.
Even if the economy is doing better, it is expected to otherwise be below their growth targets.
(If you have a more specific question, you should re-phrase your question accordingly. If you want to find someone with expertise on Chinese government policy making (not me!), I am unsure how many read this website.)
