Embargoes are prohibitions on commerce and trade with specific countries imposed for safety, protectionist, or political reasons. There are three main types of embargoes: 1) Financial sanctions like freezing assets and funds; 2) Trade sanctions on products like arms, imports/exports, and other goods; 3) Trade sanctions on services including technical aid, investments, transport, travel, and insurance. Common goals of embargoes include preventing weapons from reaching sanctioned countries and hindering their economies. Examples provided include EU sanctions on Russia and US embargoes on Cuba and Syria.
