The talks between Transport minister and taxi owners on Friday lasted more than two hours but failed to find a common ground between the minister and the taxi owners' federation SATA.
After the talks, members of the SATA delegation held a meeting at the ministry lasting over an hour and afterwards announced that they will continue strike action.
SATA's president Thymios Lymberopoulos stressed that taxi owners had gone to the meeting in good faith and wanting to find a solution based on the central points raised by the federation concerning the proposed liberalisation of the sector.
Though the minister had seemed equally keen to find a solution, he had made no commitment concerning the taxi owners proposals and had called for a month of dialogue in which he would present his own proposals, Lymberopoulos said.
SATA's president stressed that the federation considered this period excessive and had made a series of specific proposals, including a population ratio governing the number of licences issued, retaining taxi ranks in non-urban areas and other demands.
"Until the minister makes specific commitments, the strike will continue," Lymberopoulos stressed and appealed to taxi owners to avoid extremes since the sector will carry on its labour action to the "end".
Earlier, the ministry issued an announcement saying that the liberalisation of the sector will go ahead based on rules that will govern all aspects of its operation, from the issue of licences to the training of drivers and the new forms of taxis and services.
The minister will also take into account the proposals of tourism enterprises and will present its proposals to all the sides involved at the end of August.
A scheduled meeting between Ragoussis and a delegation of taxi drivers did not take place because the meeting with the taxi owners ran on too long and because many of their representatives had been unable to make the trip from outside Athens.
In Thessaloniki, traffic on the Thessaloniki-Nea Moudania national motorway was brought to a standstill on Friday when hundreds of striking taxi owners drove in motorcade from Thessaloniki to the seaside resort region of Halkidiki.
The protest was held in the afternoon while thousands of people were leaving Thessaloniki for the weekend or for their summer holidays.
Main opposition New Democracy leader Antonis Samaras on Friday appealed to striking taxi owners to act responsibly in the face of government irresponsibility and call off their strike action.
He stressed that it "sad" that Infrastructure, Transport and Networks Minister Yiannis Ragoussis had sped to reverse the measures prepared by his predecessor but did not yet have specific positions to present.
In a statement, Samaras accused Ragoussis on insisting on "barren tactics" instead of admitting his mistake and giving a way out of the problems he had created. ND's leader also asked that Prime Minister George Papandreou intervene and begin dialogue for a liberalisation of the taxi sector based on the rules that applied in all European countries.
He stressed that the government's current inconsistency and u-turns with respect to the taxi sector could not continue, especially when the tourist season was at its peak.
