The frank exchange between Canada's Prime Minister Justin Trudeau and China's President Xi Jinping at the G20 summit has drawn worldwide headlines.
The not so cosy encounter happened on Wednesday when the duo discussed an alleged leaking of details about their closed-door meeting at the Bali summit the previous day.
"Everything we discussed has been leaked to the paper, that's not appropriate, " Mr Xi told Mr Trudeau through an interpreter.
Mr Trudeau admitted in the public confrontation that the two will disagree on certain matters.
"We will continue to work constructively together," he said.
"In Canada we believe in free and open and frank dialogue," Mr Trudeau said.
Mr Xi's response via the interpreter was: "let's create the conditions first."

A Canadian government official said the leaders also discussed Russia's invasion of Ukraine, North Korea and climate change.
While they did shake hands after the talks, their body languages showed both making a swift exit in different directions.
It was the first talks between Mr Trudeau and the Chinese leader in more than three years.
Thanks for the G20 memories
The confrontation between Mr Trudeau and Mr Xi was not the first time there's been unorthodox moments at G20 summits. Some have involved Australian leaders.
Labor leader Anthony Albanese had a jovial chat with the new UK Prime Minister Rishi Sunak on the Indonesian island at G20.
The G20 was established in response to the global economic reversal that emerged from late 2007.

But that facility had to be dismantled for sensitivity reasons over concerns outsiders could potentially install listening devices, according to a 2018 book on Mr Trump by veteran journalist Bob Woodward.

He later softened his language stating he would have a robust discussion with the Russian leader during the then G20 summit.
The exchange between Mr Trudeau and Mr Xi was not the first time world leaders have been caught off guard with the cameras rolling.

Political commentator Bruce Hawker told The Feed often the G20 summits are highly stage-managed.
"I think these G20 style events always lend themselves to a bit of humour," he said.
"When you get hard-headed leaders like Putin or Xi Jinping in less formal attire it can just look slightly ridiculous because that is not the way we envisionage them," he said.
"Justin Trudeau now knows he's offended the leader of the biggest country in the world, so that is no small thing."
