Parallel to this, Lim Kok Thay, the Executive Chairman of Genting Group, was recently named the Chairman and Director of Resorts World Sentosa as of February 1, 2026. While Lee Shi Ruh manages the integrated resort's daily business, Lim Kok Thay provides high-level strategic direction and leadership to the board. This leadership team is currently overseeing a massive $5 billion expansion project known as "RWS 2.0," which includes the development of new themed lands like Minion Land at Universal Studios Singapore and the expansion of the Singapore Oceanarium.
