U.S. and others in the Group of Seven () advanced economies would end normal trade relations, known as Permanent Normal Trade Relations (PNTR) with Russia as it pursues its invasion of Ukraine.
PNTR is USAs version of Most Favored Nation (MFN).
In international trade, MFN status (or treatment) is awarded by one nation to another.
Most Favoured Nation status designation means two countries have agreed to trade with each other under the best possible terms: low tariffs, few barriers to trade and the highest possible imports allowed.
A nation with MFN status will not be discriminated against and will not be treated worse than any other nation with MFN status.
In USAs case, granting of permanent normal trade relations status is automatic, except where specifically denied by law.
