KYIV, Ukraine (AP) — Ukraine’s former president says he discussed investments with President Donald Trump’s attorney, Rudy Giuliani, in 2017, but that he never discussed Ukrainian companies with any U.S. official.

Like many Ukrainians, former President Petro Poroshenko is trying to distance himself from the U.S. impeachment inquiry into Trump, triggered by a phone call between the American leader and Poroshenko’s successor, Volodymyr Zelenskiy.

“We definitely do not want to be involved in the political process inside the United States,” Poroshenko, now a Ukrainian lawmaker, told reporters in parliament Wednesday.

Poroshenko said he met Giuliani in 2017 as a “friend of Ukraine” and they discussed “political support and investment” but nothing else. He wouldn’t elaborate.

“We never ever spoke about commercial companies” with Trump, former President Barack Obama, current Democratic presidential candidate Joe Biden, or “any U.S. officials,” said Poroshenko, Ukraine’s leader from 2014 to 2019.

Giuliani wants Ukraine to investigate Biden, whose son Hunter served on the board of the Ukrainian gas company Burisma. Trump asked Zelenskiy to “look into” the Bidens in a July phone call that is now at the center of an impeachment inquiry.

Poroshenko said he was not aware that Giuliani had met with then-Ukrainian prosecutor Yuriy Lutsenko.

Like Poroshenko, many Ukrainians are shrugging off U.S. efforts to impeach Trump as someone else’s problem.

But they are worried about one thing: that Ukraine’s role in the Trump affair strengthens Russia’s hand, and hobbles the politically inexperienced Zelenskiy just as he’s trying to tackle the problems that matter to them most: corruption and an armed conflict with Russian-backed separatists in the east that has divided their nation.

Zelenskiy announced an agreement Tuesday with Ukrainian separatists that paves the way for peace talks to end five years of fighting, but Ukrainian nationalists denounced it as capitulation to Russia.

The U.S. scandal “is weakening Zelenskiy’s standing inside the country,” said Tatyana Stanovaya, head of the R.Politik political analysis firm.

A rough transcript of the July phone call between Trump and Zelenskiy shows the Ukrainian leader flattering Trump, criticizing the U.S. ambassador and European leaders, and saying Ukraine’s chief prosecutor is “my guy.”

“He gave a reason to doubt his ability to be an honest president,” Stanovaya said. “It’s the first big blow for him” since he overwhelmingly beat Poroshenko in Ukraine’s April election.

Zelenskiy’s comments on the call will fuel the Kremlin’s view that Ukrainian leaders are beholden to U.S. interests.

As the impeachment process heats up, the U.S. State Department gave initial approval to a $39 million sale of anti-tank missiles to Ukraine to help the country battle Russia-backed separatists. The proposed aid is in addition to some $400 million in U.S. military aid released last month.
