Ukrainian Defense Minister Oleksiy Reznikov denied Ukraine was involved in the bombing of the Nord Stream pipeline, which carries natural gas from Russia to Germany. While the pipeline was not active at the time of the bombing last September, it was filled with fuel.

The denial comes after The New York Times reported that intelligence reviewed by U.S. officials suggests a pro-Ukrainian group carried out the Nord Stream bombings last year.

After the story broke, German Defense Minister Boris Pistorius warned against “jumping to conclusions” about who carried out the explosion, suggesting it could have been a “false flag” operation to blame Ukraine.

German authorities were reportedly able to identify the boat used for the sabotage operation, saying a group of five men and one woman using forged passports rented a yacht from a Poland-based company owned by Ukrainian citizens. The nationalities of the perpetrators are unclear, according to a separate report by Germany’s ARD broadcaster and Zeit newspaper.

“We have to make a clear distinction whether it was a Ukrainian group, whether it may have happened at Ukrainian orders, or a pro-Ukrainian group [acting] without knowledge of the government. But I am warning against jumping to conclusions,” Pistorius said on the sidelines of a summit in Stockholm.

A Russian diplomat said Russia has no faith in the U.S.‘s “impartiality” in the conclusions made from intelligence.

The White House is welcoming reports that Chinese President Xi Jinping plans to soon speak with Ukrainian President Volodymyr Zelenskyy for the first time since Russia’s invasion began, while cautioning that after speaking with Ukrainian counterparts, "they have not yet actually gotten any confirmation that there will be a telephone call or a video conference."

"We hope there will be," national security adviser Jake Sullivan said during a briefing on Air Force One. "That would be a good thing because it would potentially bring more balance and perspective to the way that the new PRC is approaching this, and we hope it will continue to dissuade them from choosing to provide lethal assistance to Russia."

"We have been encouraging President Xi to reach out to President Zelenskyy because we believe that PRC and President Xi himself should hear directly the Ukrainian perspective and not just the Russian perspective on this," Sullivan continued. "So, we have in fact, advocated to Beijing that that connection take place. We've done so publicly and we've done so privately to the PRC."

Sullivan said the U.S. has “not yet seen the transfer of lethal assistance of weapons from China to Russia," after previously warning it was being considered.

"It's something that we're vigilant about and continuing to watch carefully," he added.
