KUALA LUMPUR: SG4 has the potential to become a major economic hub if its four member states pool their resources and complement one another.

Describing the economic cooperation initiative involving Kedah, Kelantan, Terengganu and Perlis as a "sleeping giant", the former prime minister Tun Dr Mahathir Mohamad said the states had the land, population, infrastructure and resources to drive growth.

"If these states can get their act together, pool their resources, and complement each other, the sky is the limit," he said in a speech read by his son, Tan Sri Mokhzani Mahathir, at the SG4 Business and Economic Forum 2026 at the Kuala Lumpur Convention Centre today.

Dr Mahathir, 101, was unable to attend as he had been unwell. Mokhzani said his father had prepared the speech and wanted to deliver it personally.
