He told the press in Sarajevo Croatia had not yet met Bosnia and Herzegovina's request for the entire documentation regarding the bridge which is necessary for an assessment on the acceptability of the project.
Dokic said the documentation was requested a month and a half ago, but that only part of it was submitted. He added the request was recently repeated and that a "harsh letter" was sent to the Croatian authorities.
"We will insist that Bosnia and Herzegovina be ensured safe access to the open sea," he said, adding he was confident that Croatia would not allow itself "the political luxury" of bringing into question its overall relations with Bosnia because of the bridge.
The Croatian bridge should pass near the coastal town of Neum, where neighbouring Bosnia has a narrow outlet to the Adriatic Sea.
The southernmost part of Croatia is cut off from the rest of the country at Neum, a stretch of the coast belonging to Bosnia.
The announcement of the construction of the Peljesac bridge has provoked strong reactions in Bosnia, where some officials believe the future bridge could block the passage of ships to Neum.
One of the most important infrastructure projects undertaken by the current Croatian government, the Peljesac bridge will be 2,300 metres long and cost 250-300 million euros along with access roads. The project is expected to be completed by 2008.
