Final answer:
Negotiations and economic sanctions are diplomatic tools used by countries to influence the behavior of other nations.
Step-by-step explanation:
In the context of international relations, negotiations and the use of economic sanctions are examples of diplomatic tools that nations use to influence the behavior of other countries.
For example, the United States led negotiations with Iran in 2015 to sign the Iran Nuclear Deal, which aimed to curb Iran's development of nuclear weapons. In exchange for Iran dismantling its nuclear facilities, the deal allowed Iran to engage in trade and lifted some sanctions.
However, it's important to note that negotiations and sanctions are not foolproof and can be subject to changes in domestic politics or the actions of individual leaders.
