Boiko Borissov and Avigdor Lieberman in Jerusalem in 2010
Israeli foreign minister Avigdor Lieberman is due to meet his Bulgarian counterpart, Nikolai Mladenov, in Sofia on March 2.
The trip follows a successful high-profile visit to Bulgaria by most of the Israeli cabinet last year which cemented bilateral ties.
At the time a joint statement signed by Bulgarian Prime Minister Boiko Borissov and Israeli prime minister Benjamin Netanyahu "noted with satisfaction" progress made in relations between the two countries, a reference to agreements signed on July 7 in Sofia.
During their July meeting Netanyahu had spoken of the "chemistry" between himself and Borissov, with whom he first became acquainted at a meeting in 2007.
Lieberman has sometimes been a controversial figure on the world stage, having mooted a re-drawing of borders to enable Arab Israeli citizens (who are full citizens of Israel) to be "returned" to areas under the jurisdiction of the Palestinian Authority. He has also proposed a "pledge of loyalty" from Arab Israeli citizens.
Recently, he has appeared to change his mind regarding the viability of the creation of a Palestinian state, saying that he now favours the idea in principle.
