Subject to approval by Congress

However, under United States constitutional law, executive agreements are not considered treaties for the purpose of the Treaty Clause of the United States Constitution, which requires the advice and consent of two-thirds of the Senate to qualify as a treaty.

Explanation:

The Constitution gives to the Senate the sole power to approve, by a two-thirds vote, treaties negotiated by the executive branch. The Senate does not ratify treaties.
