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.

Treaty
A joint resolution is a legislative measure that requires approval by the Senate. It also requires approval from the House of Representatives and then requires the Presidents approval.
An executive agreement or understanding with a foreign leader might serve the immediate purpose of a treaty and lead to a formal treaty between the respective nations. A treaty requires the approval of the Senate and may be much harder to negotiate than an agreement between two men. (It also may be easier to break or worm out of if the situation changes or new information comes to light.)
