Excellency,
I have the honour to refer to the conversations which have recently taken place between representatives of our two Governments relating to the territorial application of commercial arrangements between the United States of America and Ireland, and to confirm the understanding reached as a result of these conversations as follows:

1. For such time as the Government of the United States of America participates in the occupation or control of any areas in Western Germany, the Free Territory of Trieste, Japan or Southern Korea, the Government of Ireland will extend to the merchandise trade of such areas the most-favoured-nation treatment for the time being accorded to the merchandise trade of the United States of America. It is understood that the undertaking in this paragraph relating to the extension of most-favoured-nation treatment shall be subject to the exceptions recognised in the General Agreement on Tariffs and Trade permitting departures from the application of most-favoured-nation treatment; provided that nothing in this sentence shall be construed to require compliance with the procedures specified in the General Agreement with regard to the application of such exceptions.
2. The undertaking in point 1, above, will apply to the merchandise trade of any area referred to therein only for such time and to such extent as such area accords reciprocal most-favoured-nation treatment to the merchandise trade of Ireland.
3. The undertakings in points 1 and 2, above, are entered into in the light of the absence at the present time of effective or significant tariff barriers to imports into the areas herein concerned. In the event that such tariff barriers are imposed, it is understood that such undertakings shall be without prejudice to the application of the principles set forth in the Havana Charter for an International Trade Organisation relating to the reduction of tariffs on a mutually advantageous basis.
4. It is recognised that the absence of a uniform rate of exchange for the currency of the areas in Western Germany, Japan or Southern Korea referred to in point 1, above, may have the effect of indirectly subsidizing the exports of such areas to an extent which it would be difficult to calculate exactly. So long as such a condition exists, and if consultation with the Government of the United States of America fails to reach an agreed solution to the problem, it is understood that it would not be inconsistent with the undertaking in point 1 for the Government of Ireland to levy a countervailing duty on imports of such goods equivalent to the estimated amount of such subsidization, where the Government of Ireland determines that the subsidization is such as to cause or threaten material injury to an established domestic industry, or is such as to prevent or materially retard the establishment of a domestic industry.
5. The undertakings in this Note shall remain in force until January 1, 1951, and, unless at least six months before January 1, 1951, either Government shall have given notice in writing to the other of intention to terminate these undertakings on that date, they shall remain in force thereafter until the expiration of six months from the date on which such notice shall have been given.

   Accept, Excellency, the renewed assurance of my highest consideration.
