WASHINGTON - US President Joe Biden mentioned his often strong disagreements with Henry Kissinger in a Thursday eulogy to the former US secretary of state, who died a day earlier at the age of 100.

He described his first encounter between him, then a young senator, and Kissinger, secretary of state at the time, as something he would "never forget," saying Kissinger was "giving a briefing on the state of the world."

"Throughout our careers, we often disagreed. And often strongly. But from that first briefing — his fierce intellect and profound strategic focus was evident," Biden said.
