Soundbars are super popular. Unfortunately most companies make them in China as a lot of the manufacturing steps are manual. The companies that manufacture soundbars outside of China also manufacture them in China as well. So, you have to be careful about the specific model you buy.
Samsung is a huge Korean electronics manufacturer. They make products all over the world. Some of their soundbars are made in China, while others are not. In the 2022 and 2023 model years, the Q series (starting with HW-Q) and the S series (starting with HQ-S) are made in Vietnam. These are the latest soundbars that they offer, as opposed to older ones made in China. So, make sure the model says 2022 or its the current bleeding edge one.
Yamaha is a Japanese company famous for their professional sound equipment and musical instruments. They make soundbars in China as well as Vietnam. Specifically, the YAS-109, SR-C20A and SR-B20A are made in Vietnam. Those are good budget options and are very highly rated compared to others in thier price range
