"Indonesia and the US are building or bridging relations between the Western world and Islam. If the Koran burning occurs, then those efforts will be useless," Mr. Yudhoyono wrote in a letter to Obama, according to Agence France-Presse.
His spokesman Teuku Faizasyah told reporters "there is a deep concern over the planned Koran burning ceremony as it could spark conflict among religions."
Indonesia is the world's most populous Muslim nation, and approximately 86.1 percent of the 230 million population practices Islam, according to the CIA World Factbook.
The Telegraph reported today that the personal appeal from Indonesia will put Obama, who spent four of his childhood years living in Jakarta, "under intense pressure to ban the Koran burning in order to prevent a violent backlash across the Islamic world."
