Answer:
Culture and economics.
Explanation:
Nations, given the wide interconnection that globalization has generated, have signed huge amounts of treaties with other nations, in which economic, political, cultural, social, border, security, and all legal issues that otherwise affect or benefit said countries are agreed.
But governments, in all situations, must take as their main precaution not to directly or indirectly harm the economies of the countries involved, nor in any way harm the cultural identity of those nations.
Thus, these limitations regulate the framework of agreeability under which the nations will agree on certain conditions of the treaties.
