In the United States, that power is vested in the President, but the treaties must be approved by the Senate. This is Article II, Section 2, Clause 2, of the Constitution.
The Secretary of State negotiates treaties but they must be approved by the President and ratified by the Senate.
The Senate.
Yes
true
enumerated powers
The Senate has the right of ratification.
Through the Department of State and the Department of Defense, the President is responsible for the protection of Americans abroad and of foreign nationals in the United States. The President decides whether to recognize new nations and new governments, and negotiate treaties with other nations, which become binding on the United States when approved by two-thirds of the Senate. The president may also negotiate "executive agreements" with foreign powers that are not subject to Senate confirmation. I believe the president can negotiate treaties, but they do not take effect until the Senate votes to ratify them.
Yes, of course the president can. I believe it was the Louisiana Purchase that the president bought without asking the congress. When asked that the president did not have the power to buy the land. He said that he did have the power to "negotiate" treaties.
power to make treaties with other countries..
1.the president has the sole power to negotiate and sign treaties. but must have 2/3 of senate agree to it. 2. the power to make executive agreements with other countries. these agreements have the the same legal status as treaties, but they do not require senate conduct. 3. where the united stated will recognizes government of other countries and have dealing with that government.
The Executive Branch makes the Treaty, this branch includes the President, the US Senate ratifies the Treaty by a two thirds majority. Only then is it effective.
Each country has its own rules regarding treaties, so it totally depends on the country. For example, in the US, the President has the power to negotiate treaties, but they must be approved by at least two thirds of US Senators present.
