Every time I hear about this I wonder what the Chinese and other Asian
countries do about it. Anyone know?

Wherever it comes from, there's probably something there that eats it, and helps keep it under control. Importing whatever eats it, however, might or might not be a bright idea, as whatever that is might cause its own problems. Possible predators generally need to be carefully investigated before deciding whether they can be safely imported; and this process can take years. There do seem to be people working on it:

From this page:

"A newly described species, Trissolcus halymorphae Yang (Hymenoptera: Scelionidae) is an egg parasitoid that has been identified as the primary biological control agent responsible for the management of BMSB in northern China (Yang et al. 2009). This parasitoid averages a 50% mortality rate for BMSB populations, and it was the only natural enemy identified with a mortality rate exceeding 10%. Trissolcus halymorphae is currently not known to occur in the U.S. with existing populations of BMSB."

From this page:

"Pheromone traps for this insect are under development but are not yet available commercially. Most stink bugs are attacked by a variety of natural enemies, especially insect predators and parasitoids. Research has shown that native North American beneficial insects don’t show much interest in BMSB, however, and there are no commercially available beneficial insects that effectively attack BMSB. USDA entomologists are studying the feasibility of introducing effective BMSB natural enemies from Asia that are safe and specific to the stink bug and which would offer some long-term relief."
