International trade and investment have expanded significantly nowadays; as a result, the restrictive business practice became more complex – involving many countries at the same time. In an attempt to eliminate the restrictive business practice, several countries have joined hands to form treaties. Thailand can study the weak points and strong points of these treaties in comparisons in order to find guidance in establishing free trade agreements which can benefit the country. Bilateral free trade agreement can be made in different ways including one whose procedures are specified in details and one whose procedures are defined broadly. The alternatives depend on economic power of the two countries in question. The rules binding with the treaty of each country can also be various from one to another. The cooperation can be extended to the exchange of information, the investigation by the other party, Negative Comity, Positive Comity, and the compliance with Extradition Treaty. The findings show that, the agreement best suitable for Thailand is actually the one with broad procedures which are an incomprehensive cooperation, has non-binding effect, and are limited to the exchange of the information. Under the broad procedure agreement Thailand will benefit from the exchanged information of the other country and has no obligation to follow to the procedures described in the agreement which may cause disadvantages to us. However, in the future, when Thailand has gained more experience in the prosecution of the Restrictive Business Practices, we can reconsider the agreement to seek for more comprehensive cooperation.
