Taiwan blacklists dozens of shadow fleet ships tied to North Korea smuggling networks

Dozens of freighters operating near Taiwan have been linked to smuggling networks connected to North Korea, according to a Financial Times investigation published on July 10. The vessels, predominantly Chinese-owned ships flying flags of convenience, appear on a Taiwanese maritime blacklist that the island nation uses to track and inspect suspicious shipping activity.

The shadow fleet and Taiwan’s enforcement problem

Taiwan has maintained a blacklist of at least 52 Chinese-owned shadow fleet ships since January 2025. These vessels are subject to enhanced tracking and inspection by Taiwanese authorities. The new FT probe goes further, tying many of these ships to networks implicated in smuggling goods to and from North Korea.

Taiwan banned all trade with North Korea back in 2017 to comply with UN resolutions. Taiwanese firms and individuals have been previously sanctioned or accused of facilitating illicit oil and coal transfers tied to North Korea. The UN has repeatedly targeted vessels and companies involved in ship-to-ship transfers, a common method for evading sanctions where cargo gets swapped between boats in open water, away from port inspections. Some of those designations between 2018 and 2019 involved Taiwanese-linked operators.

The flags-of-convenience angle adds another layer of complexity. Ships registered under the flag of a country different from their actual owners can obscure true ownership and make accountability a shell game.

Why crypto watchers should care (even though crypto isn’t directly involved)

One notable detail from the investigation: there are no connections to cryptocurrency assets or digital tokens in association with these maritime smuggling activities. The Lazarus Group, a North Korean state-linked hacking operation, has been responsible for some of the largest crypto heists in history. Pyongyang has used stolen digital assets to fund weapons programs, launder money, and circumvent the same international sanctions that these shadow fleet ships are also trying to dodge.

Geopolitical risk and market implications

The shadow fleet revelation adds a new dimension to an already complicated picture. Chinese-owned vessels are operating on Taiwan’s blacklist while allegedly facilitating North Korean sanctions evasion, creating a three-way diplomatic friction point. If Taiwan increases inspections or expands its blacklist, transit times through the strait could lengthen. Insurance premiums for vessels operating in the region could rise.

North Korea’s ability to sustain its sanctions evasion infrastructure, whether through shadow fleets, crypto theft, or both, directly affects the calculus around nuclear proliferation and regional security. Every barrel of oil that reaches Pyongyang through these networks undermines the international sanctions regime that is supposed to constrain its weapons program.
