"Undoubtedly, a number of countries interested in continuing the conflict will make titanic efforts to disrupt the planned meeting between President Putin and President Trump," he said in a post in his Telegram account, specifying that by efforts he meant "provocations and disinformation".

The Russian president and Trump emissary held talks in Moscow days before the White House deadline for Russia to reach a peace deal with Ukraine.

The visit is Witkoff's fifth to Moscow since Trump took office, with the special envoy at the forefront of White House efforts to end Russia's full-scale invasion of Ukraine, which began in February 2022.
