A summitry cheat sheet: How leaders connect and talk the talk at global summits

economictimes.indiatimes.com:

G20 Summit, it's a meeting marathon for Prime MInister Narendra Modi as every guest leader wants to talk to the host. During the summit, PM Modi is holding 15 bilateral meetings with other heads of states. But summit conferences are not just about bilateral meetings.

They also have various other kinds of interactions on the margins and during dinners.
Summit diplomacy, or summitry, as it has come to be called, has become an essential part of diplomacy today, and most heads of states too like summitry for the ease and comfort of negotiation at the very top which could otherwise remain stuck in lower diplomatic channels. Yet, summitry is not easy and for the novices, it could be downright risky too. Heads of states running into each other in a milieu where protocol is loose has its own rewards as well as risks.

Bilats, brush-bys and pull-asides
Summitry helps build personal chemistry between heads of states due to easy face-to-face interaction.

But multilateral summits, such as the G20, where 20 world leaders are present are complex affairs to manage due to paucity of time. They could well be called marathon speed dating as the leaders are meeting each other for very short periods.
Bilats, or bilaterals, where the two leaders sit down and talk to each other, are full-fledged meetings and the longest type. They can easily stretch beyond an hour.

But there are a lot of short formats too such as pull-asides, brush-bys and walk-and-talks. Pull asides, as the name suggests, are meetings between two leaders on the margins of the main activities where they meet for a short period which could be just 10 minutes. Brush-bys are more casual and can be even shorter.
