"I have not received any information about the security problems. Therefore, do not worry excessively," Widodo was quoted as saying by the news outlet.
Indonesian Foreign Minister Retno Marsudi admitted that notifying its citizens is the right of every state. However, she said she was puzzled as to why the United States had not informed Indonesian authorities about alleged threats in Surabaya.
"We contacted the American Embassy to exchange views on what the rationale for the so-called warning is," Marsudi said, Detik reported.
On January 3, the US Embassy in Jakarta issued a security warning for Americans in Surabaya. It said a "potential threat" existed against US-linked banks, businesses and hotels in Surabaya, recommending US citizens to be watchful while visiting these sites. The embassy provided no specific details about the nature of the threat.
On Monday, a similar travel warning was issued by the Australian Department of Foreign Affairs and Trade, which said that its citizens should be cautious in Indonesia due to the risk of a terrorist attack.
