Israel has taken issue with the president of the United Nations General Assembly, Peter Thomson of Fiji, wearing the Palestinian flag during last week's International Solidarity Day with the Palestinian People.
Israel's ambassador to the UN Danny Danon says it was unfortunate Mr Thomson wore the Palestinian flag at an UN event whose sole purpose was to slander Israel.
Mr Danon described the UN event as a cynical Israel-bashing festival.
The UN has adopted dozens of resolutions over Israel's actions and policies, many of which Israel ignores.
In February, Israel's prime minister Benjamin Netanyahu is due to visit Fiji as part of efforts to bolster Israel's standing in international forums such as the United Nations.
Mr Netanyahu said 15 countries will be at the Fiji meeting and each of them has a vote at the UN.
Traditionally, only the Marshall Islands and the Federated States of Micronesia, along with the US, always vote with Israel.
