I am an interpreter of a company in China.Sometimes I need to host the meeting with foerigners.thanks
In the US, people will sometimes say; Thank you all for coming or for your participation, and then you simply stand up. This signals that it's over.
Lawyers like to do this. It's a power play to let everyone know who's in charge. It's like a gorilla beating his chest.
You can say: "The meeting is now closed."
Hi Shenjja, I teach how to participate in and vote during a meeting, as well as how to communicate with colleagues. If you'd like to know more you can drop me a mail. Regards.
I suggest expressions that start:
It's time to...
Wrap up the meeting
(Prepare to finish the meeting, deal with the final points)
... Finish the meeting. Thank you all for coming.
Perhaps one of these:
The meeting has concluded.
The meeting has ended.
