Elections called for Feb 2 will not be enough to end the standoff, the nation's bureaucratic elite said on Wednesday.
"All stakeholders should first initiate a dialogue and make a public commitment to push for political reforms which would help the country avert a similar crisis," they said in a statement.
The meeting, which took place at the Office of the Civil Service Commission in Nonthaburi, was reportedly arranged on Tuesday evening.
It was led by the permanent secretary to PM's Office Minister Tongthong Chandransu, cabinet secretary-general Ampon Kitti-ampon and Council of State secretary-general Chukiat Rattanachaicharn.
A source said the meeting was organised to discuss their concerns about the political situation and make sure state officials understand what they can and cannot do while a new government is not yet in place.
They also emphasised that the constitutional monarchy was best for Thailand and called on government officials to follow His Majesty the King's advice in doing their jobs.
According to the source, Mr Tongthong wrote the meeting summary, read it out at the meeting and asked them to help polish the statement.
Meanwhile, a coalition of seven private organisations led by the Thai Chamber of Commerce (TCC) on Wednesday decided to take action to help ease the crisis.
Vice-chairman of the TCC Vichai Assarasakorn said the coalition would hold its first session tomorrow to formulate possible political reforms.
