Ukraine's Volodymyr Zelenskiy said on Tuesday that the war with Russia would eventually end in dialogue, but that Kyiv had to be in a strong position and that he would present a plan to U.S. President Joe Biden and his two potential successors.

The Ukrainian leader, addressing a news conference, said Kyiv's three-week-old incursion into Russia's Kursk region was part of that plan, but that it also comprised other steps on the economic and diplomatic fronts.

"The main point of this plan is to force Russia to end the war. And I want that very much - (that it would be) fair for Ukraine," he told reporters in Kyiv of the war launched by Russia's full-scale invasion in February 2022.

He did not elaborate further on the next steps, but said he would also discuss the plan with Democratic Vice President Kamala Harris and probably also with Republican Donald Trump, the two nominees for the U.S. presidential election.

Zelenskiy said he hoped to go to the United States in September to attend the U.N. General Assembly in New York and that he was preparing to meet Biden.

His remarks indicated that he sees the main potential forum for talks as a follow-up international summit on peace, at which Ukraine has said it wants Russia to have representatives.

The first summit to advance Kyiv's vision of peace, held in Switzerland in June, pointedly excluded Russia, while attracting scores of delegations, but not from China, the world's second largest economy, despite Kyiv's push to win over the global south.

Russian Foreign Minister Sergei Lavrov said on Aug. 19 that talks were out of the question after Ukraine launched a major cross-border incursion into Russia's Kursk region on Aug. 6.

Indian Prime Minister Narendra Modi, who was in Kyiv last week, spoke by phone with Russian President Vladimir Putin on Tuesday and told him he supported an early and peaceful resolution to the Ukraine conflict.
