Some businesses and brands lend themselves towards being a little cheeky with their social media accounts – Nando’s, for example.

Others, like that run by the US Defense Intelligence Agency, aren’t really the kind of platform you want to be letting rip with snarky one liners.

No wonder then that there’s a protocol row going on over at the G20 summit, with these details below from the BBC:

The tweet, which was quickly deleted, read: “Classy as always China”.

When President Barack Obama arrived in Hangzhou there was no red carpet and he had to leave by a different plane exit…

The “Classy as always China” tweet linked through to a New York Times article on the protocol incident, it said.

The DIA felt compelled to issue a speedy apology, saying the posting did “not represent the views of the DIA. We apologize [sic].”

[Obama] said that part of the reason for the tension on his arrival in China was because the US had a different attitude towards the press than other countries.

Barack spent much of the opening day of the summit deflecting questions on any simmering tension between the two countries. Despite his best efforts, things continued to unravel:

More tensions between the two sides broke out at the West Lake State House, where Mr Obama met President Xi Jinping.

White House aides, protocol officers and Secret Service agents became embroiled in a row with Chinese officials as to how many Americans should be allowed into the building before Mr Obama’s arrival. At one point there were fears the confrontation could become physical…

The president pointed out that this was not the first time there had been tension with the Chinese over security and news media access during his travels.

“But this time,” he said, “the seams are showing a little more than usual.”

Now let’s replace Obama with Trump – doesn’t have such a tame ending, does it?
