Why did President Zelenskyy criticize the Riyadh talks regarding Ukraine?

President Zelenskyy criticized the Riyadh talks because they were discussions about Ukraine conducted without Ukraine's direct participation. According to Kurt Volker, former U.S. Ambassador to NATO, any negotiations impacting Ukraine's future must include Ukrainian officials at the table. Volker emphasized the importance of consulting both Ukraine and European allies during any negotiations with Russia. He expressed skepticism about reaching lasting agreements without proper Ukrainian representation and underscored that ongoing conversations involving U.S. officials, European leaders, and Ukraine are essential to effectively address the conflict's complexities.
