CLEAN : G20: French FM meets with US Tillerson

The video tutorial begins with an introduction and confirmation of the topic, followed by an invitation to join the session. It then discusses the meeting of the counterterrorism coalition and provides a recommendation for grade points. The session concludes with expressions of thanks.

What could be the context behind the phrase 'Then join us'?

What might 'Once again, almost recommendation for your grade point' suggest about the speaker's intent?
