I'm not sure whether either of these two words fits the context. Could you please read it and see if it is OK and help me choose better option?

The phase two/The Phase Two in/of negotiation is the negotiating session itself, in other words, appointment/meeting which attempts/tries to reach an agreement.

Thank you
I'd choose meeting for the 1st.

Then "aiming at reaching", or is it too vague?
Thank you Pieanne!!Emotion: smile
