During the winter, Ukraine and Russia held three rounds of talks with U.S. mediation. No new such meetings are currently planned.
Stubb, who is in close contact with both Ukrainian President Volodymyr Zelenskyy and U.S. President Donald Trump, believes that the Iran war may be a contributing factor to the stalled talks.
But there could also be a halt in the negotiations because they have reached the end of the negotiation process and are not moving forward, the Finnish leader tells Norwegian VG.
Last weekend, Ukraine sent a delegation to the United States in an attempt to revive the process - seemingly without result.
Russia does not want to move towards peace, Zelenskyy stated on Tuesday.
