UN secretary-general Ban Ki-moon expressed his gratitude to Prime Minister Commodore Voreqe Bainimarama for Fiji's involvement in the UN Disengagement Observer Force (UNDOF) at the Golan Heights.
The Prime Minister met with Mr Ban last weekend at the UN headquarters in New York.
Mr Ban thanked Commodore Bainimarama for the speedy deployment to UNDOF in the Golan Heights.
He said this deployment was especially appreciated because it came at a time of great need for UNDOF.
Mr Ban expressed his hope that the Fijian personnel were adjusting well to the situation in UNDOF.
Fiji deployed its first contingent of military and medical personnel to UNDOF in June.
There are 501 Fijians serving under UNDOF at the Golan.
RFMF Land Force Commander Colonel Mosese Tikoitoga said Fiji was recognised in the UN as having the largest ratio of peacekeepers to its population.
He said there was relief at the passing of the UN resolution on the dismantling of Syria's chemical weapons last week, which made the threat of a military strike on Syria by the US unlikely.
However, he said the situation in Sinai was "volatile", attributed to the unrest in Egypt.
"I think we've always associated Sinai with peaceful deployment but last year, the problem started to develop as the situation worsened in Egypt. And now in our deployment areas, our people are getting shot at from stray fires," he said.
"It's not a safe deployment anymore, but nevertheless its nothing new to the Fijians deployed there. It's the same situation they faced in Lebanon, Iraq and Syria."
He said Fiji had 398 soldiers serving on the Sinai Peninsula.
