The main issue in the negotiations is seriousness and desire to promote diplomacy.
Ismail Bakai, spokesman for the Ministry of Foreign Affairs:
Our issue is not really about whether the negotiation is direct or indirect; These are completely marginal discussions. Don't forget the main thing.
We negotiated with America and reached a conclusion. America signed the agreement at the highest level, but this agreement did not last two weeks. It has nothing to do with whether the negotiation is direct or indirect.
The main issue is the existence of seriousness and determination in the promotion of diplomacy in its accepted sense; Diplomacy means recognizing the rights and interests of the other side and avoiding this approach where one side wants to take points unilaterally and leave the other side without points.
Other issues that are brought up are mainly media speculations about what certain countries asked or did not ask from Iran; In my opinion, the essence of the matter should be considered.
