In rare cases, such as Ethiopia and the Qing Dynasty in China, local governments have been able to use treaties to at least mitigate the effects of European colonization. These included learning the intricacies of European diplomatic customs and using treaties to prevent the power from overstepping its agreement or opposing different powers. [Citation required] An essential part of treaty drafting is that the signing of a treaty implies recognition, that the other party is a sovereign state and that the agreement, considered to be under international law, is applicable. Therefore, nations can be very cautious when it comes to qualifying a treaty agreement. In the United States, for example, interstate agreements are pacts and agreements between states and the federal government or between government authorities are statements of intent. The language of treaties, such as that of a law or contract, must be interpreted if the text does not appear clear or if it is not immediately clear how it should be applied in a perhaps unforeseen circumstance. The Vienna Convention stipulates that treaties must be interpreted in “good faith” according to “the ordinary meaning given to the contractual terms in context and in light of their purpose and purpose.” International legal experts also often invoke the “principle of the greatest possible effectiveness,” which interprets the language of the treaty so that it has the maximum strength and effectiveness in defining obligations between the parties. In other cases, such as New Zealand with the Maori and Canada with its First Nations and First Nations, treaties have allowed Aboriginal people to maintain a modicum of autonomy. Such agreements between colonizers and indigenous peoples are an important part of the political discourse of the late 20th and early 21st centuries, the treaties that are being discussed have an international reputation, as indicated by a UN treaty study.   If the withdrawal of a contracting state is successful, its obligations under this treaty are deemed terminated and the withdrawal of part of a bilateral treaty terminates the treaty.
When a state withdraws from a multilateral treaty, it remains in force among the other parties, unless it is interpreted differently, as has been agreed among the other States Parties. [Citation required] Bilateral agreements are concluded between two states or entities.  A bilateral contract may have more than two parts; Thus, each bilateral treaty between Switzerland and the European Union (EU) has seventeen parties: the parties are divided into two groups: the Swiss (“on the one hand”) and the EU and its member states (“on the other side”). The treaty establishes rights and obligations between Switzerland and the EU and the Member States for several years – it does not create rights and obligations between the EU and its member states.
