Former US President Donald Trump wished President Joe Biden ''good luck'' Thursday in his upcoming meeting with Russian President Vladimir Putin and also jokingly gave him some last-minute advice.

''Good luck to Biden in dealing with President Putin—don’t fall asleep during the meeting, and please give him my warmest regard!'' Trump said in a statement.

During his presidential campaign against Biden, the country 45th president nicknamed his successor ''Sleepy Joe.''

Trump said he had a ''great and very productive meeting'' with Putin when he was president and the US won the respect of Putin and Russia.
