Ukraine is looking at how to share battlefield data with allies, the country's deputy prime minister said, calling the vast trove of stored information one of Kyiv's "cards" to strengthen its position as it negotiates support from friendly countries.

"The data we have is priceless for any country," Mykhailo Fedorov, who heads Ukraine's digitalization ministry, said in an interview, adding that Ukraine is currently "very careful" about sharing it.

Vast datasets are crucial for training artificial intelligence models to recognize patterns and make predictions.
