BANGKOK, Oct. 22 (Xinhua) -- The anti-government group -- the United Front for Democracy against Dictatorship (UDD) -- has resolved they will not disrupt the ASEAN Summit; instead they plan to hand in a political petition letter to the ASEAN leaders on Friday, the Thai Defense Ministry's spokesman told Xinhua Thursday.

    On Oct. 17, Arisman Pongreungrong, a UDD core leader, announced the UDD group would stage a rally at the ASEAN Summit's venues to demand the Thai government to conduct a referendum to seek public opinion on the 1997 and 2007 constitution.

    He also said they are to submit a petition letter to the ASEAN leaders to describe the "violent suppression" by Thai government against the "red-shirt" people in April.

    The UDD group's threat had worried all of involved parties, which have been organizing the ASEAN Summit. The political rioting created by the UDD group this year has largely affected investors' confidence in the country.

    In mid-April, thousands of UDD protesters stormed into the ASEAN Summit's venues in eastern resort town Pattaya, forcing Thai government to cancel the 14th ASEAN Summit and dialogue partner countries' meetings.

    The UDD group wants to submit their petition letter to the ASEAN leaders, but the involved authorities have been discussing who will be a representative to receive the petition letter from the UDD group, Thai Defense Ministry's spokesman Thanatip Sawangsaeng said.

    The representative could be either from the Thai Foreign Ministry or from the ASEAN body, however, at this point this has not been finalized, Thanatip said.

    Thailand, which is the 2009 chairmanship of the Association of Southeast Asian Nations or ASEAN, will host the 15th ASEAN Summit and related meetings from Oct. 23-25 in southern beach resort town Cha-am and Hua Hin.

    And, in a bid to maintain security, the Thai government has imposed the Internal Security Act (ISA) ahead of the start of the Summit from Oct. 12 until 27 at the venues of the Summit and related meetings.

    A place, which will be the venue for the representative to pickup the petition letter submission from the red-shirted group at about 13.30 p.m. local time is the beach nearby the ASEAN Summit's venues, the Defense Ministry's spokesman said.

    Meanwhile, the planned venue is out of the control of the ISA law, the spokesman explains, adding the UDD group will send six persons to submit the letter to the Thai government or ASEAN representative.

    The red-shirted people with their different political view can express their opinion (through the petition letter), said Thanatip.

    "It is good that the UDD group will not disrupt the ASEAN Summit since they are Thais, who also want the Summit to be successfully hosted," said Thanatip.

    Among the six UDD persons is Arisman, who led the red-shirted protesters stormed into the ASEAN Summit in Pattaya in last April.

    The Pattaya Court issued an arrest warrant against Arisman after he led the UDD protesters to disrupt the ASEAN Summit's venues in Pattaya.

    "He (Arisman) is now released on bail, but if he is still attempting to cause chaos and damage to the country, I will instruct police to withdraw the bail and arrest him," Deputy Prime Minister Suthep Thaugsuban said earlier, according to the Thai News Agency.
