Drafted by France, the resolution authorizes the country's security forces to be supplied with weapons of a caliber of 14.5 mm or less provided that the UN has been notified at least 20 days in advance.

The notifications must specify the type, caliber, quantity and serial or lot numbers of the weapons as well as the manufacturer and supplier.

And under no circumstances, can the weapons be sold or transferred to third parties, according to the resolution.

"It remains to be seen when there can be a further easing," said a diplomat. "The hope is there won't be too many weapons entering the country, especially weapons the state cannot control."

"The number of weapons entering the country must correspond to real needs," the diplomat added.

The Central African Republic, a country of 4.5 million people, plunged into violence and chaos in 2013 after President Francois Bozize was ousted from power by Seleka rebels.

The state controls only a small part of national territory, as armed groups fight in the provinces over resources like diamonds, gold or livestock.

Since 2013, the United Nations has enforced a total arms embargo, except for exemptions approved in 2017 with French and Russian backing to equip newly formed army units.

The UN has 13,000 peacekeepers deployed in the Central African Republic.

In February, the government reached a peace agreement with 14 armed groups that led to the formation of a new government that includes representatives of the groups.
