Dubai - US President Donald Trump's sons are to inaugurate a branded golf course in Dubai on Saturday, the first public launch for the business empire since Trump took office in January.

Donald Trump jnr and Eric Trump will attend the opening of the Trump International Golf Club Dubai, developed by luxury real estate company DAMAC Properties. The launch comes amid growing concern in Washington over the president's potential conflict of interest.

In January, Trump - at the time still president-elect - said he had rejected a $2 billion deal with DAMAC in Dubai as a personal and not official move.
