US President Joe Biden responded to his Russian counterpart's invitation for a direct conversation and said he would speak to him on a specific date in the coming days.
Earlier, in an interview, Biden called Putin a "murderer", and the Russian president in response wishes him well and offered him a live dialogue.
Like Trump, Biden is known for his personal attacks on foreign leaders.
During his presidential campaign, Biden called Chinese President Xi Jinping's Democratic Party "thugs" and said that Turkish President Recep Tayyip Erdogan is a "tyrant." He also compared North Korean leader Kim Jong Un to Hitler.
In this regard, Turkish President Recep Tayyip Erdogan said on Friday that US President Joe Biden’s comments about Russia’s leader Vladimir Putin, in which he called him a “killer”, were “unacceptable” and “not fitting of a president”.
