All cable-laying ships engaged in the installation, maintenance and repair of undersea cables in Malaysian waters will be exempted from the country's cabotage policy, the transport ministry said in a statement issued late on Thursday.
Cabotage policies regulate shipping or trade activities in a country's waters or airspace.
The government revoked permission for international vessels to conduct such work in 2020 but reversed its decision in March following local and international tech companies' calls for the waiver to be reinstated.
The ministry also said the cabotage policy on vessels shipping cargo from the country's peninsula to Sarawak state on Borneo island would be reinstated from June 1.
