Trade barriers

Are you sure

Yes, I am sure. Trade barriers are not a significant economic challenge faced in East Asia. In fact, many East Asian countries have worked to reduce trade barriers through agreements such as the ASEAN Free Trade Area and the Comprehensive and Progressive Agreement for Trans-Pacific Partnership (CPTPP). The other options, aging workforce, dependence on exports, and dependence on maritime trade, are all economic challenges faced by countries in East Asia.
