The GIF-able moment came from a video posted on the German cabinet's official Facebook page and was soon all over Twitter. Following at its heel were other photos of the two interacting at the summit.

The leaders also tweeted at each other after the meeting:
.@JustinTrudeau, face nos défis communs je suis trs heureux que nous avancions ensemble avec la mme énergie et envie de faire.- Emmanuel Macron (@EmmanuelMacron) July 7, 2017
In May this year, Mr Trudeau and Mr Macron had wowed the Internet with their pics during the G7 summit in Sicily.
In the words of Twitter, "It's good to see their bromance live on."
