KYIV, MARCH 27

After three days of intense negotiations, the Trump administration, Ukraine and Russia agreed to a limited ceasefire in which the key details, including what was covered and how it will start, were disputed by the warring sides, indicating the road to a complete truce will be long and mired with contention.

The negotiations focused on easing Black Sea shipping and halting long-range strikes on energy infrastructure, relatively low-hanging fruit that both sides had experience in negotiating before the U.S. brokered indirect talks.

While much is yet unknown, here is a breakdown of the key elements of the partial ceasefire and what is at stake in the coming weeks as talks continue.

The limited ceasefire began with a rocky start

Conflicting statements emerged immediately after the talks on Tuesday. Both sides differed on the start time of halting strikes on energy sites and accused the other of violating the ceasefire.

Russia also conditioned its part in opening Black Sea shipping on the U.S. lifting sanctions, which Kyiv dismissed.

Russian officials have greeted the results of the talks with optimism, and Ukrainian President Volodymyr Zelenskyy described it as a good start, though some Ukrainian officials have expressed discontent.

"Something tells me this is more advantageous for the enemy," Ukrainian lawmaker Yaroslav Zheleznyak told the Interfax Ukraine news agency.

Stopping fighting around Black Sea shipping routes

The U.S. said Tuesday it had reached a tentative agreement with Ukraine and Russia to stop fighting and ensure safe navigation in the Black Sea in separate talks with the two sides.

Details of the deal were not released, including how or when it was to be implemented and monitored, but it appeared to mark another attempt to ensure safe Black Sea shipping after a 2022 agreement that was brokered by the U.N. and Turkey was halted by Russia one year later, in July 2023.

Russia said the Black Sea deal announced Tuesday could only be implemented after sanctions against the Russian Agricultural Bank and other financial institutions involved in food and fertilizer trade were lifted and their access to the SWIFT system of international payments was ensured.

Zelenskyy said Moscow was lying about the terms of the agreement, despite the U.S. later saying it would help restore Russia's access to the world market for agricultural and fertilizer exports.
