How France restricted Exocet support during the Falklands War

What stance did France take during the Falklands War after selling Exocet missiles to both sides?

France assisted Britain by holding back important Exocet supplies from Argentina until after the war.

Prewar arms sales differed from French policy after fighting began. Argentina already possessed French-built Exocet missiles, creating a serious threat to British ships. France nevertheless helped Britain by stopping important missile supplies from reaching Argentina during the conflict. Export control and alliance cooperation can therefore shape the effective availability of a weapon after it has entered service abroad.
