All the options are correct.
Imposing tariffs: A tariff is a tax that is applied to all goods that are subject to importation. The most frequent is the tax levied on imports, while tariffs on exports are less common; There may also be transit tariffs that are collected on products that enter one country for another
offering economic rights: The International Covenant on Economic, Social and Cultural Rights (ICESCR: International Covenant on Economic, Social and Cultural Rights, for its acronym in English) is a general multilateral treaty that recognizes economic, social and cultural rights and establishes mechanisms for their protection and guarantee . It was adopted by the General Assembly of the United Nations through Resolution 2200A (XXI), of December 16, 1966, and entered into force on January 3, 1976. It commits the parties to work for the granting of economic rights, social and cultural rights, including labor rights and rights to health, education and an adequate standard of living.
Imposing economic sanctions: these are economic and financial penalties applied between one or a group of countries to another, a group of persons (for example a community) or even a single person. When asked, they ban the afflicted nation, group or person from trading until agreements are met. By this mean, isolation to trade is forced, and therefore a policy forced into the country reluctant to comply. Passing legislation to approve treaties: this is the most civilized form of foreign policy. The decisions are made through the participation of all the powers of a federal union (executive, legislative and judicial) an example of this type of policy is NAFTA treat between the US, Canada, and Mexico.
Signing trade agreements: again, as in the previous, a group of countries agrees to establish fair and proportional economic exchange policies among all the participants of the contract. example of this are the agreements of the European Union, where each participating country shares common goods (in this case the unification of its currency = euros) in order to standardize the value of the products produced by each nation and allow a relatively free exchange of their goods between them, without distinction of frontiers (which imply tariffs)
Offering military aid: This last type of policy is perhaps the least popular (or ethical), but for developing countries, it can represent an advantage when governments are not a stable or democratic government is not predominant or in emerging democracies like many African countries. Examples of this are the sub-Saharan countries (Ethiopia, Kenya, Tanzania) to name a few.
