The Event Daily flights between Tbilisi and Yerevan are to begin March 16. This welcome news in relations between the two countries was followed by a surprisingly public spat between the offices of the two presidents. The verbal exchange is in sharp contrast to the warm talk that took place during the February visit of two senior Georgian officials – Foreign Minister Grigol Vashadze and Parliament Speaker Davit Bakradze -- paid official two-day visits to Yerevan late last month. While public statements played up positive trends in bilateral relations, both sides made the point that there are no problems that cannot be resolved jointly through "constructive dialogue" -- a tacit admission that problems do indeed exist, and that past pledges to resolve them may not always have been sincere or systematically implemented.
