Section 1377 of the Omnibus Trade and Competitiveness Act of 1988 requires USTR to review by March 31 of each year the operation and effectiveness of U.S. telecommunications trade agreements.

The purpose of the review is to determine whether any act, policy, or practice of a foreign country that has entered into a telecommunications-related agreement with the United States is not in compliance with the terms of the agreement, or otherwise denies, within the context of the agreement, to telecommunications products and services of U.S. firms mutually advantageous market opportunities in that country.
