"Singapore's busy shipping lanes are set to become a new revenue stream for the government, with a proposal to adopt a model similar to the Strait of Malacca. Under the proposed system, vessels passing through Singapore's territorial waters would be required to pay a voluntary fee. The Strait of Malacca model, which has been in place since 2004, has seen significant revenue generated from ships that transit through the busy waterway, with the fees being used to fund maritime security and other related initiatives. If implemented, the new system could provide a welcome boost to Singapore's economy, but it remains to be seen how the proposal will be received by the shipping industry."
Omani proposal is based on the Strait of Malacca model, where ships that use the strait provide voluntary fees.
