This is an exaggeration, at best. There may have been countries that grew in the latter part of 2020, but to characterize these as "booming" is misleading.
Japan had its first economic contraction since 2009 (down 4.8% over 2019). They've been flirting with deflation throughout 2020. And they're one of the countries with the lightest responses.

Developing countries in Asia are no better off:
"ADB said GDP in developing Asia will contract 0.7% this year and three-fourths of the region’s economies are set to register negative growth for 2020. That includes countries like Singapore, Thailand, India and the Philippines. China, where the coronavirus outbreak was first reported in late-December, is the only country that is expected to register a positive growth, albeit far below normal levels of growth."

Countries that failed to contain the virus like Europe and the US had negative GDP growth and racked up large amounts of debt.
You're certainly welcome to do the work to prove the (extraordinary) claim that you're making.
As I said, even if you can find a few examples of growth amidst the broader disaster, most are nowhere near what they would have been.

“ Taiwan's economy grew 2.98% in 2020 compared to a year ago, advance estimates by the island's statistics office showed on Friday — the growth outpaced China's 2.3% expansion”
I'll give you Taiwan. Now tell me about the rest of Asia.
The biggest "Asian" countries excluding China, Japan and Korea, didn't have hard lockdowns like in New York or California (Japan's constitution didn't even allow it), just voluntary social distancing and early closure recommendations, and effective contact tracing. China had lockdowns but it's economic numbers are extremely unreliable.
