Pedro Sánchez was invited to sit at the'summit' of the G20 in Osaka, in 2019. The trip was a journey rather befitting a secretary of state or a minister, with the exception of two meetings.
Sanchez is closer to Donald Trump than Joe Biden, and delegates announcements to his spokesmen. The White House is well aware of the difficulties that SánChez has in maintaining with his coalition partners his Atlanticist and pro-Ukraine Sanchez stance.
