Advisor and Presidential Commissioner for Sanctions Policy Vladyslav Vlasiuk gives a briefing on the need for Ukraine’s partners to impose interim sanctions on Russian ballistic weapons manufacturers and cut off supplies of foreign components to Russia’s military-industrial complex, Kyiv, Ukraine, on August 26, 2026.

SINGAPORE — Ukraine’s sanctions envoy said Russia could be forced to retreat from the war within six months if its oil revenues are halved, as he pressed governments across Asia to shut down loopholes letting Russian tankers and weapons components slip through the region undetected.
Vladyslav Vlasiuk, Ukrainian President Volodymyr Zelenskyy’s commissioner for sanctions policy, said during his trip in Singapore on Tuesday that sanctions remain the most effective lever to force Moscow into serious peace talks.
“Sanction is a really good way to force the Russian side to start talking,” Vlasiuk said in remarks to media at Ukraine’s Embassy in Singapore. “We also believe that sanctions so far caused a lot of difficulties for the Russian economy — a lot of constraints, a change of dynamics.”
He added that a further round of “really crushing sanctions” could put Russia “in a tricky situation” and force a withdrawal over the next six months, if oil revenues — a critical source of cash for Moscow — are cut by at least half.
The remarks came as Kyiv steps up outreach to Asia, a region increasingly viewed as a weak link in the sanctions architecture built by the U.S., European Union and Group of Seven nations, since the Russian invasion in 2022.
Indian and Chinese refiners have absorbed the bulk of discounted Russian crude, helping Moscow keep oil revenue flowing even as Western governments tightened price-cap enforcement.
Southeast Asian ports and free-trade zones have emerged as waypoints for ship-to-ship transfers that obscure the origin of sanctioned Russian cargos.
During the Asia trip, Vlasiuk said he planned to meet officials in Malaysia, Indonesia, Japan and Thailand to discuss Russia’s so-called “shadow fleet,” used to move oil without depending on Western companies and thus avoiding the imposed price ceilings, and the flow of microelectronics into Russia’s defense industry.
According to files reviewed by CNBC, components recovered from a missile shot down in the Kyiv region last month originated primarily from the U.S., Russia, China, Taiwan and Japan, underscoring how deeply embedded global supply chains remain in Russia’s weapons production, even after more than three years of export controls.
“Some of the microelectronic components used in such missiles reach Russia through the Asian region,” the Ukrainian special envoy said.
He added that the risk extends beyond Russia: “You have to be very careful about sending around certain types of mechanicals, because otherwise those would be ending up in the military-industrial complexes of terrorist countries,” including Iran and North Korea.
‘Gray zone’ tactics
Vlasiuk also warned against underestimating Moscow’s willingness to operate below the threshold of open conflict with NATO members.
Russia has escalated pressure on Ukraine’s European allies in recent weeks through a series of “gray-zone” actions designed to unsettle regional governments, as its forces struggle to gain ground in Ukraine and absorb mounting Ukrainian drone and missile strikes at home.
European authorities have linked Moscow to a rising number of drone incursions, sabotage incidents, cyberattacks, and other hostile acts across the continent in recent months.
“Wake up, people — the world has changed,” Vlasiuk said. “Russia is not that funny bear anymore. It’s not funny. It’s a bear that’s dangerous, and you have to be tight and powerful against it,” he said.
