Russia on Friday expressed concern over the expansion of British military infrastructure closer to its borders under the "centennial partnership" agreement between London and Kyiv.

"Britain is a NATO country, and the advance of its military infrastructure towards our borders is certainly a rather worrying element," Kremlin spokesman Dmitry Peskov remarked during a press briefing over the UK-Ukraine "100 Year Partnership" agreement signed the day before, adding that Moscow would analyze the agreement's implementation and its impact on the region.

Though the agreement does not equate to Ukraine's membership in NATO, Peskov emphasized that the UK's military infrastructure near Russian borders is certainly a "worrying element."

The document, signed during British Prime Minister Keir Starmer’s visit to Kyiv on Thursday, outlines extensive defense cooperation between the UK and Ukraine. The British press highlighted that the agreement, which spans 100 years, would enhance naval cooperation and grant London access to Ukrainian mineral resources.

Peskov categorically rejected this provision, saying, "This is Russia's inland sea; there can hardly be a question of cooperation between Ukraine and the UK."

Separately, Peskov commented on statements made by Scott Bessent, the nominee for US Treasury Secretary under President-elect Donald Trump, who has called for tougher sanctions against Russia’s oil sector to pressure Moscow into peace negotiations on Ukraine.

According to the Kremlin spokesman, no fundamental changes should be expected in US sanctions policy during Trump’s presidency.

“It is no secret that the American administration, while declaring political will for dialogue, will not significantly alter its character in this regard. There is no need to indulge in excessive expectations,” Peskov said.

The official added that Bessent’s support for sanctions aligns with his prospective role, stating, “It would be strange if, as a minister, Bessent did not support the decision of his president. In case of non-support, he would simply resign.”
