BANGKOK, Feb 22 (Reuters) - Supporters of Thai Prime Minister Yingluck Shinawatra, the target of weeks of sometimes violent street protests, denounced opposition threats against businesses linked to her family on Saturday ahead of a gathering of their leaders.
Anti-government protesters have blocked key Bangkok intersections with tents, tyres and sandbags, seeking to unseat Yingluck and halt the influence of her billionaire brother, Thaksin Shinawatra, an ousted former premier regarded by many as the real power behind the government.
This week they targeted businesses linked, or once linked, to the Shinawatra family, sending stock prices tumbling.
"What we don't like right now is their involvement in threatening companies on the stock exchange that is not involved with government," Tida Tawornseth, chairwoman of the United Front for Democracy against Dictatorship (UDD), told Reuters. "It's a move away from government into business."
The protests have already taken a toll on the economy, on tourism in particular, with arrivals in Bangkok sharply down.
The UDD, a "red-shirted" protest movement based largely in Thailand's populous north and northeast, is holding a meeting of its leaders from across the country on Sunday in Nakhon Ratchasima, north of the capital.
Generous subsidies for farmers in the north and northeast were a centrepiece of the platform that swept Yingluck to power in 2011, but they have left Thailand with vast stockpiles of rice and a bill it is struggling to fund.
"WE'RE NOT INVOLVED IN POLITICS"
About 500 anti-Thaksin protesters gathered this week outside the Bangkok offices of SC Asset Corp, a property developer controlled by the Shinawatra family, waving Thai flags and blowing whistles.
Yingluck was executive chairwoman of the company before being swept to power in a landslide election victory in 2011.
SC Asset's share price has lost almost 10 percent since Wednesday and mobile handset distributor M-Link Asia Corp , also with links to the family, lost 12 percent.
Other stocks affected include telecoms group Shin Corp , founded by Thaksin before he entered politics, and its mobile affiliate Advanced Info Service Pcl (AIS) which on Saturday sent an SMS to clients saying it no longer has any connection with the Shinawatra family.
"AIS is not involved in politics and is not a pipeline for any side," it said. "Dr. Thaksin and family have already sold all shares in the company since 23 January, 2006, and from then are no longer connected with the company."
Tawornseth said Sunday's rally would consolidate plans to restore democracy after the opposition boycotted and disrupted elections this month, leaving the country paralysed under a caretaker government. She ruled out any plans for violence.
