Ukraine is overhauling its minerals sector, which has been pounded by three years of war, in the hope of unlocking potential and attracting billions of dollars of investment from a minerals deal with the U.S., its ecology minister said.

The country has deposits of 22 of 34 minerals deemed as critical by the European Union for industries such as defense, high-tech appliances and green energy, as well as ferro alloy, precious and non-ferrous metals used in construction, and some rare earth elements.

However, much of the sector is underdeveloped, weighed down by Soviet-era bureaucracy and lack of investment.
