[speaker001:] Professor Wang, what is non-tariff barrier?
[speaker002:] Non-tariff barrier is another mean to restrict imports.
[speaker001:] Can you give an example?
[speaker002:] For example, some countries restrict imports by quantitative restriction.
[speaker001:] Why?
[speaker002:] This is used to protect local industries or to achieve certain political objectives.
[speaker001:] Oh, Are there other means?
[speaker002:] Technical barriers are set for imported goods.
[speaker001:] This is designed to exclude them from domestic market, isn't it?
[speaker002:] Yes, some countries may use some of the unnecessary health rules to exclude foreign food.
