SKOPJE, MACEDONIA - Macedonia's name, a source of friction with neighboring Greece, is now souring relations with Serbia.
Macedonia's foreign ministry said Serbia should avoid calling it by the "offensive" name of Former Yugoslav Republic of Macedonia, or FYROM, which Greece favors.
A ministry statement Friday said it would be "inappropriate and disrespectful" for Serbia to call its small neighbor anything but Macedonia.
While Serbia still formally calls the country Macedonia, its foreign minister has suggested a change to FYROM, and Serbian highway toll receipts now use that name.
Greece argues that the name Macedonia implies designs on a Greek province also called Macedonia.
The U.S., Russia, China, and most other countries use the term Macedonia, although the United Nations goes for FYROM. Macedonia gained independence from Yugoslavia in 1991.
