Prime Minister Prayut Chan-o-cha abruptly cancelled a press interview session at Government House Thursday, leaving the media confounded as to why the regime said it would host CEO Mark Zuckerberg in Bangkok on Oct 30.
Facebook claimed Wednesday it has no plans for any of its "senior leaders" to visit the country.
The session was called off despite a podium having been put in place and questions being gathered from journalists. Deputy Prime Minister Somkid Jatusripitak was said to be on sick leave.
On Tuesday, Gen Prayut told the media Mr Zuckerberg would visit Thailand later this month and discuss cooperation in solving transnational crimes. Mr Somkid on Monday backed up this claim.
"There are no plans currently for any of our senior leaders to visit Thailand," a Facebook statement said on Wednesday.
