Informed sources revealed to "Reuters" that U.S. President Joe Biden and his Turkish counterpart Recep Tayyip Erdogan may meet during the NATO summit in Lithuania next week. One source indicated that a brief meeting between Biden and Erdogan is likely to take place during the summit, and preparations are currently underway. Meanwhile, an American official noted that a "side" meeting between the leaders is possible, but arrangements have not yet been made. Erdogan strongly opposes Sweden's request to join the alliance, while Biden has shown strong support for it, and the issue of Sweden is likely to overshadow any discussions between them.
