Queen Elizabeth II thinks Chinese officials were “very rude.” The British royalty was caught on camera expressing her true feelings about the state visit of Chinese President Xi Jinping last year.

While the Queen met with Metropolitan Police Service Commander Lucy D’Orsi at the Buckingham Palace grounds on Tuesday, the palace’s official cameraman was able to film their discussion about Xi’s trip to Britain last year.

When D’Orsi was introduced as the officer responsible for the security during the Chinese leader’s visit, the nonagenarian was heard joking, “Oh, bad luck,” referring to D’Orsi’s assignment.

D’Orsi confided to the Queen that the state visit had been a “testing time” for her as Chinese officials appeared to have disregarded her and Barbara Woodward, the British Ambassador to China.

“I’m not sure whether you knew, but it was quite a testing time for me,” D’Orsi told Queen Elizabeth, to which she replied, “I did.”

“I think at the point that they walked out of Lancaster House and told me that the trip was off,” the police commander continued.

“They were very rude to the ambassador,” the Queen agreed.

“They were … Barbara was with me, and they walked out on both of us. It was very rude and very undiplomatic, I thought,” D’Orsi said.

A Buckingham Palace spokesperson declined to comment on the filmed conversation, only saying (via the Guardian), “The Chinese state visit was extremely successful and all parties worked closely to ensure it proceeded smoothly.”

Beijing, on the other hand, had no immediate comment.

The Queen’s comments were filmed after British Prime Minister David Cameron was also caught on camera calling Nigeria and Afghanistan “fantastically corrupt.”

Cameron was informing Queen Elizabeth of the leaders of the countries coming to the anti-corruption summit, which will be held in London on Thursday, when he said the two countries are “possibly two of the most corrupt countries in the world.”

The Queen remained silent, though Archbishop of Canterbury Justin Welby defended Nigerian President Muhammadu Buhari, saying the current leader isn’t corrupt.
