Bangkok, Monday.

THAI Foreign Minister Prasong Soonsiri said today that his Government

was considering a ban on British imports after the publication of a

British dictionary which described Bangkok as ''a place often mentioned

where there are a lot of prostitutes''.

Prime Minister Chuan Leekpai was quoted on radio as saying that

misinformation was reaching Europe that prostitution was out of control

in Thailand and that he personally believed Bangkok had no more

prostitutes than London.

Thai students demonstrated for a third day outside the British Embassy

in Bangkok today as the war of words begun last week escalated, forcing

Longman's, the publishers of the dictionary with the offending entry, to

promise that it would be withdrawn.

Student leader Pailat Panalie, 24, handed a letter to the embassy

today and said: ''Bangkok does have some brothels, but so does London.

It's offensive that Thailand should be singled out.''

Tony Wilson, political secretary at the British embassy, met the

demonstators and promised to pass on the letter to Longman's.

Thai Government spokesman Abhisit Vejjajiva said he would approach the

embassy to see if it would help resolve the problem. Britain's

ambassador, Christian Adams, was in the UK and was believed to be in

contact with Longman's.

Abhisit, who was educated in London, said that if the reference to

prostitutes in the Longman's Dictionary of English Language and Culture

was not removed, Thailand might produce its own dictionary with special

references to Britain.

The definition might run: ''England: Former colony hunter which killed

scores of natives worldwide. Capital London. Target of terrorists groups

including IRA.

''Known chiefly for an area called Soho, a sleazy area where

unattractive women plied their trade as prostitutes.''

The new Longman's dictionary defined Bangkok as: ''The capital city

and main port of Thailand. It is famous for its temples and other

beautiful buildings and is also mentioned as a place where there are a

lot of prostitutes.''

The book has been withdrawn from university libraries and the

Government is considering banning it.

The Thai Embassy in London has complained to Longman's and expressed

shock and regret.

A cover story in Time magazine last month showing a European with his

hands round a Thai prostitute also drew protests from the Thai

Government to the US Department of Foreign Affairs.

The Government spokesman added that Thais were angry, not because

there were no prostitutes in Bangkok, but because the problem was being

tackled. ''If you look for prostitutes you can find them everywhere.''

Thai Government policy had changed from the days of previous Prime

Minister Chatichai Choonavan, who, when asked about Thailand's

prostitution problem, replied: ''Our problem is that we have too many

beautiful women, don't you think?''

But others want Thailand to attack the problem, not the dictionary.

Officials say there are some 80,000 prostitutes in Thailand but

unofficial counts are far higher and 20% of the prostitutes are thought

to be under 18.

''The Government should take action instead of just being ashamed of

the international image of the country,'' said Chantawipa Apisuk, head

of a prostitutes' rights group.

In London this afternoon Longman's announced that it would withdraw

the controversial dictionary from sale in Thailand -- and change its

definition of Bangkok.

''The Dictionary of English Language and Culture draws its information

from a wide range of sources such as newspapers and magazines and is

intended to reflect the popular meaning of words it does not influence

or create new definitions,'' the publisher said.

''However we are sensitive to the feelings of the Thai people and

therefore we will withdraw the current definition from the next reprint,

planned at the end of the year.''

The row erupted as a Thai princess was beginning a goodwill visit to

London.

Princess Sirindhorn Maha Chakri is to open a six-day seminar on Thai

studies that will bring together Thai and foreign scholars.

During her 10-day visit the princess, a daughter of King Bhumibol

Adulyadej, will visit the BBC, the Red Cross, and the Royal Botanical

Gardens.

The Foreign Office was determined not to get involved in the vice row

as Princess Sirindhorn was welcomed by Minister of State Alastair

Goodlad.

A spokeswoman said: ''This is a matter between Longman's and the Thai

authorities, who are in touch on the issue.''
