Donald Trump‘s secretary of state, Mike Pompeo, has cancelled a meeting with Angela Merkel in Germany due to “pressing issues”.

Mr Pompeo had been due to meet Ms Merkel and German foreign minister Heiko Maas in Berlin on Tuesday.

The State Department said the meeting would have to be rescheduled, but gave no further details.

A spokesman cited by the US Embassy said: “Unfortunately, we must reschedule the Berlin meetings due to pressing issues. We look forward to rescheduling this important set of meetings. The Secretary looks forward to being in Berlin soon.”

Neither Ms Merkel’s nor Mr Mass’s office had any immediate comment.

According to a journalist in CNN’s White House team, reporters travelling with Mr Pompeo are flying with him to a mystery destination. Betsy Klein tweeted: “They do not know where they are going.”

Mr Pompeo has been taking part in a meeting of the Arctic Council in Finland this week.

Finnish foreign minister Timo Soini said on Tuesday there will be no joint declaration following the summit as the other members could not get the United States to agree on a text that includes language about climate change.

Instead, he said, there would be statements from ministers and Finland’s government, which currently holds the chair of the Arctic Council.

Official US statements and documents prepared for the meeting did not refer to “climate change” and their scientific focus was limited to reductions in carbon emissions that predate the administration and research.

In a roughly 20-minute speech outlining the Trump administration’s Arctic policy on Monday, Mr Pompeo acknowledged melting ice but did not use the phrase “climate change.”

The Secretary of State instead made clear that the US government saw disappearing sea ice in the world’s high north as first and foremost an opportunity to exploit rather than a crisis to mitigate.
