JAKARTA, Dec. 7 (Xinhua) -- Indonesia has threatened to impose retroactive acts against the European Unions (EU) ban on the country's airlines to enter the group's territory should the International Civil Aviation Organization (ICAO) agree with the EU ban and other peaceful solutions fail, spokesman of the Transport Ministry Bambang Erfan said here Friday.

    The spokesman said that Indonesia would soon question the stance of the United Nations aviation organization ICAO on the EU restriction on Indonesia's 51 airliners, including Garuda, since June after the rampant air accidents in the country that killed hundreds of lives.

    Erfan said that should the ICAO supports the EU ban, the banned country could impose a retroactive action.

    "If the ICAO agrees and other solution fails, we also can impose a ban. (But) That is the last option," he told Xinhua.

    However, the spokesman said that Indonesia would put priority on dialogue and other peaceful settlements on the dispute on the aviation.

    On Nov. 28 at its meeting in Brussels, the European Commission refused to lift its ban on 51 Indonesian airlines, including Garuda carrier. But it lifted its ban on Pakistan International Airlines (PIA) and on Blue Wing Airlines of Surinam.

    On Thursday, Indonesia grounded a budget airliner of Lion Air after a piece of its wing fell off at the middle of runway at the main airport of Soekarno-Hatta in the capital Jakarta.

    Also on the day, Indonesian Transport Minister Jusman Syafii Djamal said, "should the ICAO tolerate the EU ban, it would trigger a war of bans."

    But he said that the restriction on the European airliners would be the last option.

    The minister said that Indonesia wanted at least one out of three airliners that are undergoing acceleration to quit from the EU ban, with Garuda airline being the first.

    The minister was quoted by the transport ministry online as saying that Indonesia would persistently conduct improvement on its aviation and cooperate with the EU, but if it is unfruitful, Indonesia will terminate the talks on open-sky policy with the EU.

    "Bilateral agreement recently with the EU becomes lame," he said.

    Indonesia has suffered from rampant air accidents in recent years that have claimed hundreds of lives.

    On New Year's Eve, local carrier of Adam Air carrier with more than 100 people on board lost contact and disappeared in the waters of central Indonesia, and in March a Garuda Indonesia plane-200 with 140 people on board overshot the runway in Yogyakarta province and burst into flames, killing 21 people.
