Russian President Vladimir Putin ranked No. 1 on Forbes magazine's latest list of the world's most powerful people.
Putin dislodged U.S. President Barack Obama, who came first last year.
The U.S. magazine has produced a list every year since 2009.
Forbes says it takes into account several factors to "select the 72 people that matter from the 7.2 billion people on the planet," such as their influence and the financial resources they control.
Chinese President Xi Jinping ranked third, followed by Pope Francis and German Chancellor Angela Merkel.
UN Secretary-General Ban Ki-moon ranked 32nd to become the most-powerful Korean on the list, followed by Samsung Electronics chairman Lee Kun-hee (41st) and President Park Geun-hye (52nd).
Meanwhile, North Korean leader Kim Jong-un ranked 46th, down two notches from last year.
