"It [Singapore] is next to the Straits of Malacca, the most heavily used shipping channel in the world and vital to the Chinese economy."

RSN = Republic of Singapore Navy. 

South China Sea. Singapore enters the fray! FONOP! From Strategy Page and thanks to same.

"Forces: Singapore Confronts China"

"August 30, 2021: Singapore recently took part in a very visible confrontation with China. In late July there was a major international FONOP (freedom of navigation operations) in the South China Sea to confirm international access and defy Chinese claims to offshore resources across most of the South China Sea and control over who enters these waters."

"The late July FONOP was carried out by a carrier task force led by the new British carrier Queen Elizabeth, accompanied by seven other ships, including an American destroyer and frigates from the Netherlands, Britain and Singapore. There were also two other Singapore Navy ships; an amphibious assault vessel and an offshore patrol vessel."

Malacca vital to the Chinese economy but also for the economies of Singapore, Taiwan, Japan, South Korea. Of most vital importance the shipping of Middle Eastern OIL!
