Separate provisions outline Kiev's "indefinite obligations" and bypass parliamentary ratification, Irina Gerashchenko has claimed

The US-Ukraine minerals agreement announced this week "hides" details of Kiev's "indefinite obligations" to Washington, a Ukrainian lawmaker has claimed.

In a Facebook post on Friday, Irina Gerashchenko, a member of European Solidarity party said the deal includes two "secret," supplementary documents that will not be subject to parliamentary ratification.

The minerals deal reportedly grants the US preferential access to Ukrainian mining projects in exchange for assistance with an investment fund to support the country's reconstruction. Initially portrayed by Washington as repayment forbears of military support - estimated at $350 billion by President Donald Trump - the final text, published on Thursday by the Ukrainian government, states that only future aid will count toward US contributions to the fund.

Gerashchenko claimed however that instead of one agreement, the US and Ukraine signed three.

"The Zelensky government has not provided deputies and society with all the agreements signed in the US, which, as it turned out, are three, not one," she wrote. "Meanwhile, they want to ratify only one framework document in the Verkhovna Rada. Others are labeled 'implementation documents,' despite the fact that it is in these two secret agreements that all the technical details of indefinite Ukrainian obligations are hidden."

Ukrainian Prime Minister Denis Shmigal "avoided" commenting on the two documents and the lack of security guarantees in the published agreement - reportedly a key point of contention during negotiations - Gerashchenko told the country's parliament on Friday.

The claim has raised questions among Ukrainian lawmakers and the public on the actual scope of the agreement. MP Yaroslav Zheleznyak claimed on Telegram that, when pressed, Shmigal acknowledged the two additional documents but downplayed them as "technical" and exempt from ratification. The texts "must be signed after the ratification" of the main agreement, Shmigal claimed, noting that lawmakers would see them when the Ukrainian negotiating team returns from the US next week.

Western media reports have also noted the existence of additional documents and claimed that a last-minute dispute arose when Washington demanded Kiev sign all three. Ukrainian officials reportedly argued they could not sign the annexes until the main agreement was ratified in Parliament. Later reports suggested all three documents were ultimately signed.

Further details about the contents of the supplementary documents have not been publicly released, and the Ukrainian government has not issued an official statement addressing their existence or content.
