Billiard balls and playing cards. Belgium is world leader in both.

Edit: forgot to add pigeons. Belgian competition pigeons are the most expensive in the world.

Edit 2: Belfries. Clock-O-Matic is a Belgian company and world leader in the automation of Belfries. It’s not that hard because most Belfries are located in Belgium and France, if not all of them.

Edit 3: It never ends. Roller coaster wheels. Let that sink in. No their country produces more roller coaster wheels nor is as good as we arr at it.

Germany: bread

Say what you will about the chaebols running the country and the rampant corruption, Korean roadworkers are incredibly fast and efficient. There’s never some guy standing around doing nothing.

Germany: We moved our power creation from 60% coal and atom-driven to 60% wind and solar-driven in the last 6 years. This change is fundamental and can’t be reversed. We stopped our atom plants and have a plan out of coal. Even though our geography isn’t in favor for renewables, our country is dedicated in becoming carbon neutral. This is supported by most of the population and industry. (Yes renewables are cheaper than coal, gas, and atom)

Still open is the transition of heat and cars to electricity. Rather an emotional debate - Germans are car-crazy. The car discussion is similar to the gun debate in the US.
