President Biden unveiled new sanctions Thursday targeting influential Russians and President Vladimir Putin’s yachts on the 99th day of Moscow’s invasion of Ukraine — but two oligarchs linked to his son Hunter Biden again were spared.

The slow rollout of sanctions comes despite the president threatening “swift and severe” penalties ahead of the invasion, which began Feb. 24.

New US-targeted individuals include the steel and gold-mining oligarch Alexey Mordashov, Putin-linked money manager Sergei Roldugin, billionaire property developer God Nisanov, electronics executive Evgeny Novitsky, banker Sergey Gorkov and Russian Foreign Ministry spokeswoman Maria  Zakharova.

The Treasury Department also sanctioned two yachts that Putin allegedly co-owns and the Monaco-based yacht brokerage Imperial Yachts and its Russian CEO, Evgeniy Kochman.

The US released photos of the Russian leader’s alleged pleasure boats — the Russia-flagged Graceful and Cayman Islands-flagged Olympia — but did not specify their current whereabouts.

“Putin has taken numerous trips on these yachts, including a 2021 trip in the Black Sea where he was joined by Alyaksandr Lukashenka,  the OFAC-designated corrupt ruler of Belarus, who has supported Russia’s war against Ukraine,” the department added.

Washington also “targeted two additional yachts linked to Putin, Shellest and Nega, which are owned by the Russian company Non-Profit Partnership Revival of Maritime Traditions,” the Treasury Department said.
