肯定有五毛说这是假新闻

伊朗外交部官网:
Chinese ambassador summoned to Iran Foreign Ministry
"The protest of the government of the Islamic Republic of Iran regarding the repeated support of the Chinese government for the baseless claims stated in paragraph 26 of the final statement of the joint meeting of the People's Republic of China and the United Arab Emirates was conveyed to him along with a protest note."

这个新闻国内都报道了，有什么可否定的？
再说，中国在三个岛的问题上也并没有持有什么立场，只是希望政治解决这三岛的问题，并没有战伊朗或者阿联酋；原文条款：二十六、中国支持阿联酋旨在根据国际法准则通过双边谈判以和平解决三岛（大通布、小通布和阿布穆萨）问题的努力，从而根据国际法理解决该问题。
