Since Russia invaded more than four years ago, Ukraine has become a global leader in military drone innovation, enabling its forces to grind a much larger enemy to a stalemate.
asserted
Ukraine → invade → stalemate
But this technological force multiplier has come with an unsettling vulnerability: Ukrainian drone makers are highly dependent on electronics made by China, a key Russian ally.
asserted
makers → come → China
Ukraine’s greatest fear is that the Chinese government could severely restrict its access to these critical parts.
uncertain
government → restrict → parts
It also worries that Russian defense companies that need these same supplies could be given preferential treatment by Chinese factories.
uncertain
that → worry → factories
Over the past two years, Ukraine has sought to break its dependence on China by expanding domestic manufacturing and importing more supplies from Taiwan, Europe and the U.S. That has minimized its need for Chinese-made electric motors, flight controllers and other parts.
asserted
That → seek → motors
Yet Ukraine cannot entirely break free from China, whose lower costs and vastly greater production capacity cannot be matched by allied suppliers.
asserted
costs → break → suppliers
“If China stops their production to us ... we are blinded,” said Andrii Taganskyi, an executive at Odd Systems, a Ukrainian weapons manufacturer that develops cameras for drones.
asserted
that → stop → drones
China has tightened controls on exports of drones and related equipment for several years, citing concerns about prolonging the war in Ukraine.
asserted
China → tighten → Ukraine
While the restrictions have not stopped the flow of Chinese components to Ukraine, they have caused delays and driven up costs, pushing Ukrainian companies toward intermediaries in third countries.
asserted
they → stop → countries
“China has leverage,” said Robert Tallost, a researcher at the think tank RUSI.
asserted
Tallost → have → tank
“They could direct more material to Russia while restricting supplies to the West.”
uncertain
They → direct → West
China’s Foreign Ministry said Beijing takes a “prudent and responsible” approach to military exports.
asserted
Beijing → say → exports
It said it opposes the use of civilian drones for military purposes, and urged all sides to find a political settlement of the war.
asserted
it → say → war
Switching away from China would be expensive
Ukraine has earned worldwide recognition for its cutting-edge drone industry, designing and assembling systems that have changed modern warfare.
asserted
that → switch → warfare
Yet many of the materials and components that go into Ukrainian drones cannot be localized anytime soon.
asserted
that → go → drones
Magnets, motors, chips, thermal sensors, battery cells and more still largely come from China, a dozen Ukrainian manufacturers said.
asserted
manufacturers → come → China
Switching entirely to Western alternatives could raise costs by as much as 60% and cut production by a similar amount, said Oleksandr Yakovenko of TAF Industries, a major Ukrainian defense company.
uncertain
Yakovenko → switch → Industries
That is not a viable tradeoff, Yakovenko and other executives said.
asserted
Yakovenko → say → ?
Still, Ukrainian drone makers have begun to wean themselves off of China.
asserted
makers → begin → China
Three years ago, the Ukrainian drone maker Vyriy relied upon China for nearly 90% of the components in its attack drones.
asserted
maker → rely → drones
“Today, about 70% to 80% of our components are made in Ukraine,” said Vyriy’s founder, Oleksii Babenko.
asserted
founder → make → Ukraine
This increasing self-reliance has an extra benefit in the midst of a grueling war.
asserted
reliance → increase → war
Drones and drone components made domestically can be redesigned in a matter of days to meet urgent demands on the battlefield, whereas it can take months for such changes to filter through foreign supply chains, said Artur Savchii, an analyst at the Kyiv-based think tank Serpens Center for International Security.
asserted
Savchii → make → Security
At the beginning of 2024, nearly 90% of Ukraine’s imported drone parts came directly from China.
asserted
% → import → China
In the first eight months of 2026, it was just 28%, according to Ukraine Customs data.
uncertain
it → accord → data
But the drop may not be as dramatic as it seems.
uncertain
it → seem → ?
Many components recorded as coming from Poland and the Czech Republic, for example, very likely were manufactured in China and routed through those countries.
asserted
components → record → countries
Thermal cameras show why China is hard to replace
Ukraine can assemble batteries but must import the cells inside them.
asserted
Ukraine → show → them
Motors require imported magnets and copper.
asserted
Motors → require → magnets
And while Ukraine can manufacture some electronics, Chinese companies can produce them at far greater scale and roughly half the cost.
asserted
companies → manufacture → scale
Thermal cameras show just how difficult it is for Ukraine to break its dependence.
asserted
Ukraine → show → dependence
Ukrainian companies design the cameras themselves but still rely on imported sensors, which detect infrared radiation, and lenses that cannot be made domestically, manufacturers said.
asserted
manufacturers → design → radiation
One of the key raw materials is germanium, an element which China has in abundance, making Chinese lenses far cheaper than European alternatives.
asserted
lenses → have → alternatives
Although the U.S. and Europe also make sensors, most of them are used domestically.
asserted
most → make → them
Ukraine could build thermal cameras entirely from European components, Taganskyi said, but capacity and cost are barriers: Europe produces about 600,000 thermal sensors a year, versus Ukraine’s estimated need for 4 million, he said.
uncertain
he → build → million
For now, some Chinese components remain essential.
asserted
components → remain → ?
“Without this 5%, there is no camera,” Taganskyi said.
asserted
Taganskyi → be → %
Ukraine competes with Russia for Chinese components
To be sure, Russia is even more dependent on China than Ukraine, experts say – in part because of Western sanctions that restrict its access to other markets.
asserted
that → compete → markets
The difference is that Moscow doesn’t face the risk of its allies in Beijing tipping the scales in favor of Ukraine.
asserted
allies → face → Ukraine
Ukrainian President Volodymyr Zelenskyy addressed Russia’s advantage vis-a-vis its relationship with China during a recent interview.
asserted
Zelenskyy → address → interview
…and 18 more, not listed.
