BUERGENSTOCK, Switzerland, June 16 (Reuters) - Saudi Arabia, India, South Africa, Thailand, Indonesia, Mexico and the United Arab Emirates were among countries participating at a summit on peace for Ukraine that did not sign a final communique, the Swiss government said on Sunday.

Switzerland, which hosted the summit, said over 90 countries took part in the talks, and the vast majority of them signed up to the communique, according to a list which the Swiss organizers posted at the close of proceedings.

Brazil, which was listed as an "observer" on the list of attendees, also did not feature as a signatory.
