them of the foreign currency which is earned when their undertakings export to a third  country.

In application of this principle, the Member States undertake not to give exporters of coal or  steel, under the regulation referred to above, greater advantages in the use of foreign  currency than those accorded under the regulations of the Member State in which the products  originate.

The Commission is empowered to see to it that this is done by making recommendations to  governments after consulting the Council.

Article 19

If the Commission finds that the establishment of the common market, by causing a change  from direct exporting to re exporting, is leading to a shift in the pattern of trade with third  countries which causes substantial injury to one of the Member States, it may, at the request  of the government concerned, require producers in that State to insert a destination clause in  their sales contracts.

CHAPTER 3

EXCEPTIONS FROM MOST FAVOURED NATION  TREATMENT

Article 20

1. As regards the countries entitled to most favoured nation treatment under Article I of the  General Agreement on Tariffs and Trade, Member States shall jointly approach the  Contracting Parties to the Agreement to arrange that the provisions of that Article shall not be  a bar to the application of the provisions of the Treaty.  If necessary, a special session of the  GATT shall be requested for this purpose.

2. As regards countries not parties to the General Agreement on Tariffs and Trade but entitled  nevertheless to most favoured nation treatment under bilateral agreements in force,  negotiations shall be opened once the Treaty has been signed. Should the countries concerned  not consent, the agreements shall be amended or denounced as provided therein.

If any country refuses its consent to Member States or to any one of them, the other Member  States undertake to give each other effective assistance, which may extend to the denunciation  by all Member States of agreements with the country in question.
