Speaking to reporters on board Air Force One on Sunday he was asked if he would consider ending the suspension.
"We just about have. We just about have," he said.
CIA Director John Ratcliffe said on Wednesday the US had halted intelligence sharing with Ukraine, piling pressure on Ukrainian President Volodymyr Zelenskiy to co-operate with Trump in convening peace talks with Russia.
The suspension, which could cost lives by hurting Ukraine's ability to defend itself against Russian missile strikes, followed a halt to US military aid to Kyiv.
US officials will meet on Tuesday with a Ukrainian delegation in Saudi Arabia in part to determine whether Ukraine is willing to make material concessions to Russia to end the war.
Also hanging over the talks in Jeddah is the fate of a minerals deal between Washington and Kyiv.
Trump expressed optimism about the talks.
"We're going to make a lot of progress, I believe, this week," he said.
Zelenskiy and Trump had been slated to sign the minerals accord - which would give the US access to certain mineral resources in Ukraine - before Zelenskiy's White House visit erupted into a clash between the two leaders, after which it was not signed.
Trump said on Sunday he thought Ukraine would sign the minerals agreement, which Ukraine wants to contain a US security guarantee.
"They will sign the minerals deal but I want them to want peace ... They haven't shown it to extent they should," he said.
Trump also said his administration was looking at a variety of things with respect to tariffs on Russia and that administration officials are not concerned about.
Zelenskiy confimed he was also planning to travel to Jeddah.
"Tomorrow we will continue working for peace - I will visit Saudi Arabia," he confirmed on Sunday evening in his daily video address, in which he also confirmed his participation in the negotiations.
The first talks between the negotiators have already been satisfactory, Zelensky added.
"We hope for results, both in terms of peace and further support."
Meanwhile, Ukraine's military authorities said Russian soldiers attempted to retake the Ukrainian-held town of Sudzha in Russia's western Kursk region by sending soldiers through a gas pipeline.
The effort was "discovered in time", by an air reconnaissance team and repelled with missiles, artillery and drones, Ukraine's general staff said late on Saturday.
The claim could not be independently verified. Russian military blogs had earlier reported the attempted assault on Sudzha.
The pipeline used was reportedly part of a system that supplied Russian gas to Europe until early this year.
Last northern summer, Ukrainian forces seized parts of the Kursk region in a surprise counterattack. In recent months, however, heavy fighting has pushed them back.
Ukrainian troops in the region are reportedly facing further difficulties, possibly due to the US halting intelligence-sharing, including satellite imagery.
Zelenskiy has called the Kursk offensive an important bargaining chip in potential negotiations with Moscow.
The Russian encroachment through the gas pipeline is part of an offensive to eject Ukrainian soldiers from the western Russian region of Kursk, pro-Russian war bloggers say.
The ruse was among moves aimed at cutting off thousands of Ukrainian soldiers in the region ahead of Ukrainian talks with the US on a possible peace deal to end the war.
Ukrainian troops seized about 1300sq/km of Russia's Kursk region in August in what Ukraine said was an attempt to gain a bargaining chip in future negotiations and to force Russia to shift forces from eastern Ukraine.
Russia has been pressing its push to regain control of the region with some success in recent days.Â
