Greece and its international creditors agreed on Friday on the cost of the tax relief measures announced by Prime Minister Alexis Tsipras at the Thessaloniki trade fair last week, said a government official.

The time period over which the measures will be applied depends on fiscal developments in 2018 and 2019, said the official.

Asked about which measures will take place first, the official said they may be changed around without this meaning they will be dictated by international creditors.

"We have the rank preference, we hear their positions, we may have made some mistake, maybe some measure could be better for growth and be brought forward," said the official.

Talks between the two sides also focused on Friday on reforms and the increase to the basic salary.

In regards to an earlier story from Athens Macedonian News Agency saying that creditors have agreed to cancel pension cuts, rather than just delay them, the official said that this cannot be true since there are no negotiations between Greece and lenders taking place in Athens right now, just talks.

"Lenders could not agree nor disagree in regards to pensions as there are no negotiations," the official added.
