In simple terms
An arms embargo is a rule that stops weapons and other military goods from reaching a particular country, armed group or person. It is one type of sanction: a penalty that stops short of military force.
The aim is to cut off the tools of violence and push the target to change course in the interest of peace and security.
How it works
Embargoes can be imposed by the UN Security Council, by regional bodies such as the European Union, by groups of countries or by a single government.
Mandatory UN Security Council embargoes are legally binding on every UN member state. Countries must enforce them on their territory and apply them to their own citizens, ships and aircraft abroad. Some other embargoes are political commitments only.
An embargo usually covers far more than guns. It can include ammunition, military vehicles, spare parts, military training and technical advice, and it applies to supplies sent through brokers and other go-betweens. Some embargoes allow exemptions, such as protective gear for UN personnel.
Scope varies. The UN arms embargo on Sudan, first imposed in 2004, covers the Darfur region rather than the whole country.
Why it matters
Embargoes aim to shrink the flow of weapons that fuel wars and abuses. Their effect depends on enforcement, so each UN sanctions regime is run by a committee chaired by a member of the Security Council.
They sit within a wider toolkit. Since 1966, the Security Council has set up 31 sanctions regimes, ranging from broad trade sanctions to targeted measures such as arms embargoes, travel bans and financial restrictions.

Example
Diplomats warned that the arms embargo would mean little unless neighboring countries stopped weapons from crossing their borders.
Often confused with
Comprehensive economic sanctions. These restrict trade with a country broadly. An arms embargo is a targeted measure aimed only at weapons and military support.
