The idea a negotiated trade agreement is actual a path for trade doesn't exist in most of the world.
When the Indian high court decided the cost of giving pharmaceutical patents was more than the country could afford caused patents to be fodder. When the Japanese require every imported car to be individually tested instead of testing the model trade agreements mean little. When the Chinese are seeking to make all the sub-assemblies for their exports a trade agrement is out-of-date.
You don't take trade agreements to the bank, you need cash.
