Answer:
My firm would respond by lobbying.
Step-by-step explanation:
My firm would lobby (i.e. try to influence the decision of officials) the government of Thailand and ask them to stop the administrative trade barriers. My firm would also lobby government of US to end the tariff which they import on exports to Thailand. This way my firm would continue the operations of Hong Kong and Malaysia.
This shows that targeted trade barriers are effective and can damage the economy. It can discourage the trade barriers and ensure that they are removed.
