GENEVA — Secretary of State John Kerry and Russia’s foreign minister, Sergey V. Lavrov, will meet next week to discuss Syria, according to a statement released by the United Nations on Tuesday, after senior Russian, United States and United Nations officials meeting in Geneva failed to make headway on plans for a peace conference.

Plans for the Kerry-Lavrov meeting provided the only concrete detail to come out of more than five hours of talks between Wendy R. Sherman, the United States under secretary of state for political affairs; two Russian deputy foreign ministers, Mikhail Bogdanov and Gennady Gatilov; and the United Nations special representative for Syria, Lakhdar Brahimi.

The terse statement issued at the end of their meeting said that Russia, the United States and the United Nations would consult further to determine the date of a conference and complete the list of participants. Mr. Gatilov told journalists that these were among the questions on which they had failed to agree. Ms. Sherman, who was due to join the Russian officials for informal talks over dinner, made no comment.

Before the meeting started, Mr. Brahimi said he doubted any conference could take place in July and expressed hope that the major powers and regional powers would act to contain a conflict that was “getting out of hand.”
