乌克兰驻美国大使周二透露，特朗普政府采取了不寻常的步骤，警告乌克兰政府去年年底对俄罗斯黑海石油设施的打击影响了美国在哈萨克斯坦的投资。
“我们一直听到，乌克兰对新罗西斯克的袭击影响了一些通过哈萨克斯坦进行的美国投资。我们也从国务院得知，我们应该避免……攻击美国利益，”斯特凡尼什娜大使在新闻发布会上表示。
斯特凡尼什娜表示，她就此事收到了美国国务院发出的正式外交照会（demarche）。美国有线电视新闻网已联系国务院请求置评。
这一消息发布于俄罗斯入侵四周年纪念日，这场残酷的战争仍无结束迹象。美国促成的和平谈判几乎没有突破迹象。发出这一外交照会的不寻常举动似乎反映了政府的优先事项，且是在特朗普去年决定停止对基辅的新军事援助之后。
乌克兰大使表示，美国并未建议基辅停止攻击俄罗斯军事和能源基础设施。
“这与美国经济利益受到影响这一事实有关，”她说，“我们对此予以关注。”
去年11月底，乌克兰无人机袭击了黑海港口新罗西斯克，不仅损害了俄罗斯的利益，还破坏了一条关键管道，导致哈萨克斯坦石油出口大幅下降。雪佛龙公司（Chevron）是里海管道联盟（Caspian Pipeline Consortium）的主要股东，该联盟负责将哈萨克斯坦油田的石油输送至黑海出口。
然而，在乌克兰遭遇十年来最寒冷的冬季期间，俄罗斯正大幅扩大对乌克兰城市和能源基础设施的导弹与无人机打击——乌克兰和欧洲官员称这些袭击是蓄意对乌克兰平民施加苦难的行为。
US warned Ukraine’s ambassador over strikes on Black Sea oil target

The Trump administration took the unusual step of warning the Ukrainian government that its strikes on a Russian Black Sea oil facility late last year had impacted US investments in Kazakhstan, the Ukrainian ambassador to the US revealed Tuesday.
“We have been hearing that Ukrainian attacks to Novorossiysk affected some of the American investments which are being performed through Kazakhstan. And we have heard from Department of State that we should refrain from, from, you know, attacking American interests,” Amb. Olga Stefanishyna said at a briefing.
Stefanishyna said she had received a demarche, which is a formal diplomatic notice, from the US State Department over the matter. CNN has reached out to the State Department for comment.
The news comes on the fourth anniversary of Russia’s invasion with no end to the brutal war in site. US-brokered peace talks have shown little sign of a breakthrough. The unusual move to issue the demarche appears to speak to the administration’s priorities and follows Trump’s decision to halt new military aid to Kyiv last year.
The Ukrainian ambassador said the US did not suggest Kyiv should refrain from attacking Russian military and energy infrastructure.
“It was related to the very fact that American economic interest was affected there,” she said. “We have taken the note on that.”
In late November, Ukrainian drones struck the Black Sea port of Novorossiysk, damaging not just Russian interests but also a key pipeline which led to a significant drop in Kazakh oil exports. Chevron is a major shareholder in the Caspian Pipeline Consortium, which carries oil from Kazakh oil fields to the Black Sea for export.
Still, the communication came as Russia was vastly expanding its own missile and drone strikes on Ukrainian cities and energy infrastructure in the midst of Ukraine’s coldest winter in a decade – attacks described by Ukrainian and European officials as a deliberate effort to inflict suffering on Ukrainian civilians.
