More than 350, 000 travellers were stranded three weeks ago when a few thousand demonstrators from the ultraroyalist People's Alliance for Democracy (PAD) stormed the airport. Investor confidence has been badly shaken and analysts say that lost tourism business could cost 1 million jobs.
But Mr Kasit told an audience of astonished diplomats and foreign journalists on Friday that the protests were "a lot of fun".
"The food was excellent, the music was excellent," he explained.
Stranding hundreds of thousands of foreigners and Thais was excellent. Causing billions of baht of damage to the Thai economy was excellent. Illegally trying to overthrow the government and getting the foreign ministry in return was excellent.
Many observers believe that the PAD was able to conduct its protest with impunity, and help topple an electorally popular administration, because it enjoys backing from powerful anti-Thaksin elements in the army and the royal palace.
The army is responsible for airport security but did nothing to prevent demonstrators from hijacking one of Asia's most important aviation hubs.
It is widely reported that senior army figures were instrumental in persuading MPs to switch sides to the new coalition. Asked what role the army played in bringing his party to power Mr Kasit said, "I don't know".
The new prime minister, Abhisit Vejjajiva, has promised to bring the PAD to justice. Yet, besides his pick for foreign minister being a prominent supporter of the group, one of PAD's top leaders is a prominent MP in Abhisit's Democrat party.
Marky Mark by his actions is proving what a phony he is to the entire world. In terms of a corrupt cabinet, business as usual. In terms of taking orders from above, busines as usual.
Dr Pasuk Phongpaicit of Bangkok's Chulalongkorn university said, "It can't be denied that the PAD was instrumental in bringing the Democrats to government. So I think we are going to be disappointed with what this government will do about enforcing the rule of law with respect to the PAD and its activities." Foreign Minister Kasit berated Western diplomats and the foreign media for not being more sympathetic to the PAD's cause.
I can't believe this idiot will be the face of Thailand to the world.
TC is right. This cabinet is a horror show. Abhisit is a joke, a liar, and a prisoner.
