Several hundred Thai protestors gathered at Government House and the Defence Ministry in Bangkok Friday to demand a tougher stand against Cambodia for its arrest of seven Thais along the two countries' border, according to dpa. The demonstrators called for the resignation of Thai Defence Minister Prawit Wongsuwan for allegedly failing to respond adequately to the arrest of the seven Thais by Cambodian authorities on charges of trespassing on Cambodian territory on December 29. The protestors identified themselves as members of the Thai Patriots Network, which had earlier planned to march along the border near the Thai town of Aranyaprathet to voice their outrage at the Cambodian government. "For the time being we won't go to Aranyaprathet," said Thai Patriots Network leader Chaiwat Sinsuwong. "But our duty still remains." Chaiwat insisted the seven arrested Thais, including member of parliament from the ruling Democrat Party Panich Vikitsreth and Veera Somkwamkid, an activist in the nationalist movement known as the yellow shirts, had been on Thai territory when they were detained by Cambodian troops. During an earlier court hearing in Cambodia, Panich's lawyer said he had been visiting a border village "to address the complaints of [Thai] villagers," adding that the villagers had alleged that a border marker had been moved by Cambodians to encroach on Thai territory. The protestors' proposed protest march along the border has been strongly opposed by the Thai government and by residents of the area who depend on cross-border trade for their livelihoods. Earlier Friday, representatives of the New Politics Party, an offshoot of the yellow-shirted People's Alliance for Democracy, submitted a letter to Prime Minister Abhisit Vejjajiva demanding that he revoke a border agreement signed in 2000 due to alleged violations of Thai sovereignty by Cambodian forces. Deputy Prime Minister Suthep Thaugsuban on Friday criticized the Thai Patriots Network and its allies for playing politics with the already volatile Thai-Cambodia border situation. "Although the patriots have the constitutional right to peaceful assembly, they are obligated not to cause any disruptions to the people," Suthep said.
