perceived favoritism

[Lawforjustice]

Помогите перевести фразу "perceived favoritism".
Встречается в следующем контексте:
What probably doomed Kyoto was the absence of some key players. Large developing nations like China, India and Indonesia were excused from the treaty, since limiting their emissions was seen as likely to limit their burgeoning economies. The U.S., whose participation was necessary if the treaty was going to succeed, cited this perceived favoritism when it abandoned Kyoto altogether in 2001.

м.б. Когда США, чье участие было необходимо для успешной реализации Киотского протокола,окончательно выщли из него в 2001 году, они сослались на проявление явного протекционизма в отношении этих трех стран.
