BRUSSELS, April 29 (Reuters) - Apple will continue to constructively engage with the European Commission to comply with landmark EU tech rules, the iPhone maker said on Monday after EU regulators labelled its operating system for iPads as a gatekeeper under the rules.

"Our focus will remain on delivering the very best products and services to our European customers, while mitigating the new privacy and data security risks the DMA (Digital Markets Act) poses for our users," Apple said in a statement. (Reporting by Foo Yun Chee)
