Russia and Ukraine have agreed to a ceasefire before the end of the year in eastern Ukraine. 

This is the latest effort to end a bloody conflict between Ukrainian forces and pro-Kremlin separatists in the Donbass region. 

The U.N. says the fighting has killed more than 13,000 people in just over five years, one of the worst acts of violence in modern European history. 

Ukrainian President Volodymyr Zelenskiy and his Russian counterpart Vladimir Putin met at a peace conference in Paris and decided to take the first steps toward de-escalation. 

But talking to CGTN's Anand Naidoo, two experts explained just how hard that process is likely to be.
