Saudi Arabia met with NBA stars and major US sports leagues to discuss their sports' future in the Gulf, a move rights groups say is an attempt to "sportswash'' its reputation on the world stage.

The Saudi General Sports Authority paid US consultants Churchill Ripley LLC $22,000 a month to set them up with stars like Kobe Bryant, the National Hockey League (NHL), and Major League Baseball (MLB), the Guardian reported, citing documents filed under the Foreign Agents Registration Act.

Under federal law, US companies working with "agents of foreign principals in a political or quasi-political capacity" must notify the government, as happened in this case.

Saudi Arabia wants international sport to be a new stream of income, part of crown Prince Mohammed bin Salman's Vision 2030 project to modernize Saudi Arabia.

So far, the kingdom has secured contracts with World Wrestling Entertainment (WWE), and hosted legs of Formula-E racing and PGA European Tour golf.

Most recently Saudi Arabia landed the rights to host the rematch bout between Anthony Joshua and Andy Ruiz Jr, likely the biggest boxing event of 2019.

Rights groups have lambasted countries like Saudi Arabia for "sportswashing," a term for using popular athletes and sporting events to enhance an otherwise questionable reputation.

The term was coined by Amnesty International, who used it to criticize Manchester City's owner Sheikh Mansour, from Abu Dhabi.

Saudi Arabia's reputation is still suffering after the murder of the Washington Post journalist Jamal Khashoggi in October 2018.

The UN's investigation into his death concluded there was "credible evidence" bin Salman is responsible.
