KYIV, Aug 21 - Greek Prime Minister Kyriakos Mitsotakis pledged Monday to keep up military support for Ukraine for as long as it takes and to help with post-war reconstruction.

President Volodymyr Zelenskyy suggested that might mean Greece could help train his country’s fighter pilots on new Western aircraft, though Greek officials did not comment, The Associated Press reported.

Zelenskyy was in Athens for his fourth visit to a European Union capital in three days, and he also attended an informal meeting of Balkan leaders with top European Union officials.

In statements following his talks with Zelenskyy, Mitsotakis voiced full support for Kyiv against Russia’s invasion and condemned Russian for “war crimes.” He pledged to “stay on the side of the government and the heroic people” of Ukraine, “however much time may be required.”

Mitsotakis also said NATO-member Greece would participate in the “titanic” task of reconstruction in Ukraine when the fighting is over.

Zelenskyy thanked Mitsotakis for Greece’s support, and suggested that Athens has agreed to train Ukrainian pilots to fly the U.S.-made F-16 warplanes that Denmark and the Netherlands have pledged to provide to Kyiv.

“Today we have an important result for the aviation coalition — Greece will take part in training our pilots on F-16s,” he said. “Thank you for this offer.”

Greek officials did not respond to requests for comment, and Mitsotakis made no reference to pilot training.

Zelenskyy and Mitsotakis also signed a joint declaration on Greece supporting Ukraine joining NATO, “when allies agree and conditions are met.”

In the evening, Zelenskyy joined an informal dinner organized by Mitsotakis for nine Balkan leaders, European Commission President Ursula von der Leyen and European Council head Charles Michel.

The dinner was to discuss the western Balkans’ future in the EU, which many of the region’s countries have already joined and the rest are jockeying to enter.

A joint statement issued after the dinner meeting voiced support for a “re-energized and re-focused” EU enlargement process that would lead to the western Balkans, Ukraine and Moldova becoming “full-fledged members of the European family.”

Greece has joined its NATO and EU partners in strongly backing Ukraine against the Russian invasion and has provided military assistance in the form of armored personnel carriers and ammunition.

But Athens has resisted pressure to provide Kyiv with a Russian-made air defense missile system stationed on the southern island of Crete. Greece is engaged in a substantial weapons procurement program of its own amid testy relations with neighboring Turkey — its NATO ally and historic regional rival.

Zelenskyy flew to Greece from Denmark, which together with the Netherlands on Sunday announced they would provide Kyiv with F-16 warplanes that could be delivered around the end of the year.

The presidents of Serbia, Montenegro and Moldova, the prime ministers of North Macedonia, Kosovo, Bulgaria, Croatia and Romania, and the head of the council of ministers of Bosnia and Herzegovina attended Monday’s dinner. (ap/ez)
