Most are made here these days:

I have a 2016 Thai GX270 in my chipper/shredder. Quality engine all around, lots of cast iron parts, you could hit the starter with a hammer all day without breaking it, start at first pull and uses little fuel and no oil. In short it's as good as you'd expect any Honda product to be.
I also have one of the first GCV160 they made in Thailand in my lawnmower. Yes, it's a crappy little homeowner engine, but sees a fraction of the use the GX sees, only mowing the lawn in front of the house. It starts with no issue, uses little fuel and is good enough to mow the lawn despite "living" next to one of the woodpiles all year around, Winter included. Compared to the B&S and Kohler units in the same class (let alone the Chicom junk) it's a star. I know Robin/Fuji/Subaru has engines in that class which are supposed to be as good if not better but they are rarer than hen teeth around here.
