U.S. Secretary of State Rex Tillerson plans to skip a meeting with NATO foreign ministers next month in order to stay home for a visit by China’s president and will go to Russia later in April, U.S. officials said on Monday, disclosing an itinerary that allies may see as giving Moscow priority over them.

Tillerson intends to miss what would have been his first meeting of the 28 NATO allies on April 5-6 in Brussels so that he can attend President Donald Trump’s expected April 6-7 talks with Chinese President Xi Jinping at Trump’s Mar-a-Lago resort in Florida, four current and former U.S. officials said.

Skipping the NATO meeting and visiting Moscow could risk feeding a perception that Trump may be putting U.S. dealings with big powers first, while leaving waiting those smaller nations that depend on Washington for security, two former U.S. officials said.

Trump has often praised Russian President Vladimir Putin, and Tillerson worked with Russia’s government for years as a top executive at Exxon Mobil Corp, and has questioned the wisdom of sanctions against Russia that he said could harm U.S. businesses.
