Barack Obama has said the interest of the US in the Scottish independence referendum issue was to ensure it retained a "strong, robust, united and effective partner".
But the US president told reporters in Brussels the decision was "up to the people of Scotland".
The Scottish government has previously said that an independent Scotland would retain close ties with the rest of the UK and the United States in the event of a "Yes" vote in the referendum, which will be held on 18 September.
