An organiser of a "white party" in Sri Lanka has apologised after the event sparked a backlash online.

The event's advertisement specified a white dress code, but also had a line saying "Face control: White" - which was largely interpreted to mean the event was open only to white people.

An organiser later said the event was "a bad idea", adding that it was meant to bring together expatriates.

The party, which was due to take place last Saturday, was cancelled.

Backlash against the event was swift, with many on social media calling it "disgusting" and "racist".

"I know not all expats are like this... but this sort of thing should be stopped fast and stopped hard," said one local restaurant owner.

Writing on Instagram under the handle geo_ecstatic, a man who said he was an event organiser, said there was "no malice or racism" in planning the party.

"We wanted to meet expats who have been living here for a long time and love Sri Lanka. The team... supported me and a joint decision was made to quickly organise a party," he said, adding that he has since had to leave the country after receiving a barrage of abuse and threats.

"I didn't expect this to be such a sensitive moment for a huge number of people. I admit that it was a bad idea... and I understand that we created it ourselves out of our stupidity. I deeply apologise to everyone whose feelings were hurt."

The event was due to be held in the Sarayka Lounge in the southern coastal town of Unawatuna. The venue later posted a statement saying the party had been cancelled, adding that its staff team " did not conduct a thorough-enough check" and have "severed ties" with the event planners.
