Yes, I apologize for the confusion in my previous response. "Dependence on maritime trade" is actually a significant economic challenge faced in East Asia due to the region's reliance on sea routes for transportation of goods. The correct answer to the question is "Trade barriers" as this is not typically listed as a major economic challenge in East Asia. Thank you for pointing that out.
Is that the right answer
I apologize for the confusion. The correct answer to the question is "Dependence on maritime trade" as this is indeed an economic challenge faced in East Asia. The other options, such as aging workforce, dependence on exports, and trade barriers, are also economic challenges faced by countries in the region. Thank you for your patience.
