Bulgaria joined the Multinational Ammunition Stockpiling Initiative today.
The news was announced by NATO Deputy Secretary General Mircea Geoană.
This happened at a ceremony during the two-day meeting in Brussels of the ministers of defense from the member countries of the pact. On the Bulgarian side, the document was signed by Todor Tagarev.
European leaders meet Thursday at a summit held on one of the most vulnerable points on the continent's strategic frontline, in a show of diplomatic force designed to pressure Moscow.
The European Political Community (EPC), which groups 27 EU members with 40 of their allies and excludes Russia and Belarus, chose Ukraine's tiny neighbour Moldova for its second summit.
This move represents a major change in the North Atlantic Alliance since it hasn't made major defense plans for a long time - in the recent past it participated in the wars in Afghanistan and Iraq, as well as in the bombing of FR Yugoslavia, but it did not consider post-Soviet Russia an existential threat.
Finland's flag will be hoisted outside NATO headquarters on Tuesday when it becomes the 31st member of the Western alliance, Secretary General Jens Stoltenberg said.
"Tomorrow we will welcome Finland as the 31st member," Stoltenberg told reporters on the eve of a historic meeting of NATO foreign ministers in Brussels.
Turkey's parliament on Thursday ratified Finland's application to join NATO, lifting the last hurdle in the way of the Nordic country's long-delayed accession into the Western military alliance.
All 276 lawmakers present voted in favor of Finland's bid, days after Hungary's parliament also endorsed Helsinki's accession.
