So, remember that in the early 90s, Yugoslavia was getting sliced and diced into many little countries. Here's a map for those who don't remember their 8th grade geography class:
One chunk of the land was being fought over between the Serbs (who the Russians preferred), and the Kosovar Albanians. Now, the Kosovar Albanians had a wide diaspora and all were pitching into the accounts of Bukoshi. But making things slightly complicated, there were actually TWO factions within the same group of Kosovar Albanians. One was the Kosovo Liberation Army team, Gashi/Thaci. The other team was headed by Bukoshi. Both factions were nagging the top dogs at the EU/US to pleeeeaaaase pay attention to Kosovo and help them get the land away from the Russian-supported Serbs. These factions didn't necessarily agree with one another, and traditionally they've been feuding clans, but they did on the importance of claiming the land. In that mission they united. Once this mission was accomplished in 1999, however, they went back to bickering.
As to the Gashi/Thaci Kosovo Liberation Army, The US State Dept at the time listed them as a terrorist group--they had tons of drugs, weaponry, you name it. The US was more partial to the Berisha/Bukoshi team, and wasn't too interested in getting involved. But European power brokers nagged the US to change their mind and support team KLA instead. The US accepted, for reasons that I assumed had to do with a quid-pro-quo in the Middle East conflict that would begin just two years later. In 1998, the KLA became best buddies with the US. By 1999, European and American forces (under Bill Clinton) bombed the ever living shit out of Kosovo with the KLA doing the ground work.
The whole 1999 bombing campaign resulted in a hand-off of land to the Kosovar Albanians (hence getting a place called Kosovo--they got there fast and then they'll take it slooooow, that's where they want to go... way down in Kosovoooo).
The European Children's Trust did more work in the refugee camps here.
Other countries of work:
Russia: I couldn't find much in the way of work in Russia around this time. Partnership for EveryChild--the "advocacy and research" wing for the organization, claims it had partners (ie, programs but maybe not in this country) "for over 20 years" which would mean since at least 1996. It wants to achieve more of the same, which is foster care, deinstitutionalization, and helping with disabilities.
Partnership for EveryChild points to their Russian website, which only gives returns beginning in 2012. It's clear they have strong hooks in St Petersburg and Leningrad, given a mention of "working as a team with experts in child protection, specialists in social work, judges, prosecutors, police, doctors, teachers and other professionals in the field of social security and protection of the rights of children."
Georgia: By around the beginning of 2000, the Trust began doing preliminary work in this region as well.
Macedonia: They worked in refugee camps here.
