Greater Malaysia
Singapore, Malaysia, Brunei and Riau as a single english speaking Malay state?
All the commonwealth ship building work would go out there. The nation's oil wealth would promote industrialisation and growth of singapore as a financial centre. Colonisation, an intensive education program (for skilled industrial and office workers) and migrant workers would make english the first language. the China (+ Hong Kong) US, India, SA and Austalia would be major trading partners (add Japan later). A better negotiation of the Anglo-Dutch Treaty of 1824 would gain Riau and it's islands while the dutch need not make payment of £100,000.
