In 2019, the Penan and Berawan natives near the Mulu national park staged a blockade against a logging company encroaching their lands nearby Mulu for logging and oil palm plantation.[25] The Sarawak government denied that the logging activities would affect the ecology of Mulu National Park.[26] On 15 March 2019, the natives then decided to lodge an official complaint to UNESCO in hopes to bring attention to the issue.[27]
