Foreign Minister Surapong Tovichakchaikul said the government is increasingly concerned about the deteriorating situation in Egypt, where a crackdown on protesters calling for the reinstatement of ousted president Mohamed Morsi has resulted in heavy loss of life.
"As a country that is committed to upholding democratic principles and non-use of force, Thailand joins a large number of countries in condemning the excessive use of force which could only lead to further violence and undermine efforts to return to the democratic process and achieve inclusive national reconciliation in the interest of all Egyptian people," the ministry said.
Mr Surapong called on all parties to exercise utmost restraint and refrain from further violence.
He also urged the interim government to ensure the safety and security of foreign nationals residing in Egypt.
Mr Surapong said his ministry is closely monitoring the situation and will immediately evacuate Thai citizens from Egypt if the political violence worsens.
The ministry has issued a level-three security warning for Egypt on a scale of four.
The foreign minister said about 2,000 Thai citizens - 1,820 students and 200 workers - are in Egypt, mostly in Cairo.
The Thai embassy had notified them to stay alert for a possible evacuation notice and prepare necessary items such as medicine and clothing.
Meeting points had already been arranged and coordinators appointed for each of them, the minister said.
The ministry has also coordinated with Egypt Air to fly Thais to third countries if an evacuation proves necessary. Ships and other vehicles have also been prepared for sea and land evacuations.
Mr Surapong said the ministry had asked Turkey, Jordan, the United Arab Emirates and Greece to be lenient in granting visas to Thai nationals in the event of evacuation.
The Royal Thai Air Force will also help fly them out of the country if necessary, he said.
So far, no Thais have expressed an intention of returning home, Mr Surapong said.
The minister also denied reports that Thai students in Egypt were upset with the ministry's arrangements. He rejected allegations that the ministry's response had been slow.
Mr Surapong said authorities were capable of evacuating all Thais in Egypt should the violence reach the maximum level four on its security scale. He told Thai citizens to strictly abide by a warning issued earlier by the Thai embassy in Cairo.
On Thursday, the embassy told Thai citizens to remain indoors and refrain from travelling to nine high-risk locations.
The warning came after security forces on Wednesday stormed two huge Cairo protest camps occupied for weeks by supporters of Mr Morsi, leaving at least 600 dead.
Prime Minister Yingluck Shinawatra said yesterday she had instructed the Foreign Affairs Ministry to set up a panel to take care of Thais in Egypt.
The air force is also preparing a C130 transport plane to help in case of evacuation, she said.
