Indonesia's former president Susilo Bambang Yudhoyono has paid tribute to former Singapore prime minister Lee Kuan Yew in a video uploaded onto his official YouTube channel.

Mr Lee died on March 23 at the Singapore General Hospital where he had been warded for severe pneumonia since Feb 5. He was 91.

In the video, which was uploaded on March 23 and has since garnered over 1,000 views, Dr Yudhoyono said that Mr Lee devoted his whole life to delivering remarkable progress to Singapore.

Mr Lee "has worked hard to develop close relations with Indonesia," he added.

"I consider Mr Lee Kuan Yew a personal close friend, and I know he is a true friend of Indonesia," Dr Yudhoyono said.

Recounting his meetings with Mr Lee during the course of his presidency, Dr Yudhoyono said: "In everyone of those meetings he always gave me valuable motivation and advice for the success of Indonesia."

He ended the tribute by saying, "He will be sorely missed not just by Singaporeans, but by Indonesians, and by Southeast Asians."
