REPUBLIKA.CO.ID, BERLIN -- The Ukraine conflict, Islamic State group jihadists and the wider "collapse of the global order" will occupy the world's security community at an annual meeting in Germany from Friday.

Also on the agenda of the three-day Munich Security Conference (MSC) will be Iran's nuclear talks, the Syrian war and mass refugee crisis, West Africa's Ebola outbreak and cyber terrorism.

German Chancellor Angela Merkel is among 20 heads of government and state on the guest list, along with 60-odd foreign and defence ministers including US Secretary of State John Kerry and Russia's top diplomat Sergei Lavrov.

Ukraine's President Petro Poroshenko and US Vice President Joe Biden will also join the 51st MSC, a gathering launched at the height of the Cold War that is expected to focus heavily on the new East-West standoff over Ukraine.
