Apple Inc. Chief Executive Tim Cook has called for stronger privacy regulations that prevent the misuse of data in the light of the controversial leak of Facebook user information.

Cook called for "well-crafted" regulations that prevent the information of users being put together and applied in new ways without their knowledge during a session on global inequality at the annual China Development Forum in Beijing on Saturday.

His comments will ramp up pressure on Facebook Inc. and other technology companies that rely on the huge reams of data gathered from billions of people to power their products, services and sales. Facebook co-founder Mark Zuckerberg belatedly apologized for failing to better control its customers' data following reports that it let Cambridge Analytica amass information on 50 million users. The social network's shares have tumbled 14 percent following the reports.
