Officials warned that these vessels remain a major source of income for Moscow while threatening the Baltic’s cables, pipelines and fragile environment. Sweden’s foreign minister said both countries can still move faster on intelligence sharing and on responding to Russian activity in the region. The EU has already blacklisted more than 200 of the tankers, but Brussels is weighing additional steps, including more frequent inspections at sea. The goal, officials say, is to ensure that unsafe ships can no longer slip through the Baltic with little scrutiny.
