Ukrainian President Volodymyr Zelensky says he is certain the war with Russia will end sooner than it otherwise would have done once Donald Trump becomes US president.

Zelensky said he had a “constructive exchange” with Trump during their phone conversation after his victory in the US presidential election.

He did not say whether Trump had made any demands regarding possible talks with Russia, but said he'd not heard anything from him that was contrary to Ukraine’s position. BBC reported.

Trump has consistently said his priority is to end the war and stop what he says is a drain on US resources, in the form of military aid to Ukraine.
