If Ukraine has agreed to this in good faith, and not because they were coerced, the following things that stood out to me might not be as concerning as I think they are. I am also not a contract lawyer and am responding based on how the current administration sees things and reading the text as a layperson.
The maximum percentage of ownership of the Fund’s equity and financial interests to be held by the Government of the United States of America and the decision-making authority of the representatives of the Government of the United States of America will be to the extent permissible under applicable United States laws.
Sounds like the US will be seeking a disproportionate percentage of the fund.
The Government of Ukraine will contribute to the Fund 50 percent of all revenues earned from the future monetization of all relevant Ukrainian Government-owned natural resource assets (whether owned directly or indirectly by the Ukrainian Government)
This is not tied to the shares, so even if Ukraine's percent is extremely small they still have to fork over 50% of revenues from the listed resources. This also incentivizes the fund to push for exploiting resources in areas that may currently be off limits for environmental reasons, because that increases the amount of resources.
The Fund, in its sole discretion, may credit or return to the Government of Ukraine actual expenses incurred by the newly developed projects from which the Fund receives revenues.
The fund gets to offload expenses onto Ukraine. There is no matching text for offloading expenses to the fund or to the US. Sounds pretty shitty to me.
The Fund's investment process will be designed so as to invest in projects in Ukraine and attract investments to increase the development, processing and monetization of all public and private Ukrainian assets
Let's get external companies involved in reconstruction so they can benefit at the expense of Ukraine and make money off of it. Sounds like it wants to suck as much money as possible out of Ukraine.
The Fund Agreement will provide, inter alia, an acknowledgment that both the Fund Agreement and the activities provided for therein are commercial in nature.
So, the US government is running a business here and not an arm of the government. This is most likely designed to allow companies and billionaires to have all the power in the agreement so they can abuse Ukrainian resources for their own benefit. It also looks permanent, not a temporary situation to get Ukraine back to normalcy.
