Saudi Arabia and France inked on Monday a memorandum of understanding (MoU) for a 6-billion-euro ($7-billion) Saudi investment to construct three theme parks near Paris, including one likely to be manga-themed, the French president's office said.

The French presidency's Elysee Palace said the agreement for the "colossal" project was signed during a two-day visit to France by Saudi Arabia's de facto ruler, Crown Prince Mohammed bin Salman (MBS).

The investment will see the construction of three theme parks near Cergy-Pontoise, some 30 kilometers (19 miles) northwest of Paris, it said.

French President Emmanuel Macron on X hailed the "unprecedented announcement," saying the attractions would be a "new global destination."

The project will be led by an investment firm Qiddiya, a subsidiary of Saudi Arabia's sovereign wealth fund.
