A picture of the ministry's table linen juxtaposed with Louis Vuitton's popular monogram has been circulated on social media along with opinions criticising the ministry for allegedly infringing the fashion house's intellectual property.
In the ministry's monogram, the LV is replaced with the Thai letter Phor Mor, the initials of the ministry's full name.
The flower and star graphics of the ministry's table linen also look very similar to that of Louis Vuitton's "monogram canvas".
The ministry on Friday issued a statement denying the accusation.
The fabric was brought by a private event organiser hired by the ministry to organise an event to celebrate the 11th anniversary of the ministry on Thursday, the ministry said.
The fabric was used as table linen at the venue.
The ministry also denied the linen was used by senior officials at the ministry as had been claimed in social media posts.
"The fabric was removed by the organiser after the event, so no such cloth is being used by ministry officials," the ministry said.
