ANKARA/WASHINGTON, March 25 (Reuters) - Turkey and the

United States want to remove obstacles to defence industry

cooperation, a Turkish Foreign Ministry source said on

Wednesday, after talks between the NATO allies' top diplomats in

Washington.

On Tuesday, Turkish Foreign Minister Hakan Fidan kicked off

a two-day visit to Washington, where he was expected to ask

Secretary of State Marco Rubio and other U.S. officials to

remove U.S. sanctions on Turkey and allow it back into a crucial

fighter jet program.

The visit comes as Ankara seeks warmer ties with

Washington under the administration of President Donald Trump

and just days after a phone call between Trump and Turkish

President Tayyip Erdogan that a top Trump aide described as

"transformational".

The top Turkish diplomat's visit also comes at a critical

time for Erdogan, after his main political rival and Istanbul's

mayor, Ekrem Imamoglu, was jailed pending trial on Sunday,

prompting the largest anti-government protests in over a decade.

Ties between the U.S. and Turkey have drifted away from a

strategic partnership in recent years as disagreements between

the two long-standing treaty allies have widened.

The administration of former President Joe Biden kept Turkey

at arm's length over what it saw as the fellow NATO member's

close ties with Russia. Under Trump, who views Moscow much more

favorably, Ankara is hoping for a warmer relationship with

Washington. It also plans to capitalize on the personal ties

between the two leaders.

During the meeting between Fidan and Rubio on Tuesday, both

sides "clearly put forth their political will to lift obstacles

to cooperation in the defence industry field," the source said,

adding they also followed up on matters discussed between Trump

and Erdogan.

"Technical talks will be held for the resolution of existing

problems," the person added, without elaborating.

During his first term, Trump initially ignored advice from

his aides to impose sanctions on Turkey under its Countering

America's Adversaries Through Sanctions Act (CAATSA) over

Ankara's acquisition of Russian S-400 air defence missile

systems in 2019. He then took the step in 2020.

That acquisition also led to Turkey's removal from the F-35

jet program, where it was a manufacturer and buyer. Ankara says

its removal is unjust and illegal, and has demanded to rejoin or

be reimbursed for its investment in the program.

Conversations between the allies on how to resolve the S-400

deadlock were ongoing under Biden. Turkey had pledged to keep

the systems non-operational, a source familiar with the

discussions said, but a breakthrough never came.

A Turkish official, requesting anonymity, told Reuters ahead

of Fidan's visit that Ankara was aiming to agree with Washington

that keeping the S-400s non-operational can be enough to resolve

the matter.

RUSSIA IMPACT

During the Biden era, the allies had settled into a new

phase of relations, with a more transactional focus rather than

based on shared values, as differences over policies on Syria,

the war in Gaza, and judicial matters persisted.

Since coming back into office on January 20, Trump upended

Biden's policy to isolate Moscow and provide unwavering support

to Kyiv and instead focused on ending Russia's war in Ukraine.

His shift spooked European leaders who feared Washington could

be turning its back to Europe and bolstered Ankara's role as a

potential partner in reshaping European security.

The Turkish official said discussions between Washington and

Ankara had "taken a new dimension" after Trump's shift in

approach to Moscow.

"If U.S. sanctions on Russia are to be lifted, it becomes

illogical for CAATSA to be implemented on third countries. As

much as this issue is about Turkey-USA ties, it is also about

Turkey-Russia ties," the official added.

Sources familiar with the matter said the phone call between

Erdogan and Trump may bring positive momentum to conversations

in coming days, though no promises were made.

"The president had a great conversation with Erdogan a

couple of days ago. Really transformational, I would describe

it," Trump's special envoy for the Middle East Steve Witkoff

said in an interview with right-wing podcaster Tucker Carlson.

Exclusion from the F-35 program pushed Turkey to purchase 40

Lockheed Martin Block-70 F-16 fighter jets. However,

despite agreeing on the procurement, there has been little

progress on the acquisition for months.

The Turkish source said Fidan and Rubio also discussed head

of state-level visits to be held in the coming period, without

elaborating.

The two also emphasised the importance of stability in Syria

and in the Balkans, while discussing efforts to end the

Russia-Ukraine war, and the need for a ceasefire in Gaza, the

source added.
