History

Historical Context

The United Nations Convention on the Law of the Sea (UNCLOS), adopted in 1982, established comprehensive maritime rights and responsibilities, replacing earlier treaties. With 168 signatories, including Malaysia, which depends on the Strait of Hormuz for 20% of its oil, UNCLOS reflects ongoing geopolitical tensions, particularly as Iran's exclusion of the U.S. from this crucial passage underscores historical struggles over maritime control.
