BEIJING — An activist wanted by the Hong Kong government said he was denied entry to Singapore over the weekend for what he presumes were political reasons. Law is one of a number of Hong Kong activists who have left the city in recent years after the adoption of a National Security Law that has put others in prison. It noted that Hong Kong police have issued a warrant for Law's arrest under the city's National Security Law. Singapore has an extradition agreement with Hong Kong but it doesn't appear to cover national security crimes. Hong Kong police issued warrants for Law and other self-exiled activists in 2023 and offered rewards of 1 million Hong Kong dollars ($127,600) for information leading to their arrest.
