Taipei  - A Taiwan firm on Friday threatened to sue the Ukrainian government for breaking a contract allowing this firm to renovate a Kiev stadium for the Euro 2012 football championship.

Archasia Design Group (ADG), in a statement released to the Central News Agency, said it will take legal action to resolve the dispute regarding Ukraine's terminating the contract, but ADG will ask its subsidiary company in China to sign a new pact with Ukraine to renovate the stadium.

ADG blamed Ukraine for creating political obstacles to bar ADG from carrying out the contract, possibly due to Taiwan's lack of diplomatic ties with Kiev.

On April 16, ADG beat 18 contestants to win the bid to renovate the Olympisky Stadium in Kiev for Euro 2012, which will be co-hosted by Ukraine and Poland.

The 84,000-seat stadium, built in the 1920s, is due to host five Euro 2012 matches including the final.

The budget for the refurbishing is about 200 million euro (314 million US dollars).

ADG won the contract because it aimed to preserve the original style of the stadium.

However, on June 19, Ukraine's Ministry for Family, Yuth and Sort notified ADG to provide Ukraine - before the afternoon of June 20 - legal verification of all ADG's documents related to the contract. If the deadline was not met, Ukraine would annul the contract. ADG said the deadline was impossible to meet.

"This request is neither lawful nor reasonable because it takes many days to complete the verification due to our two countries' lack of diplomatic ties," ADG said in the statement.

ADG also blasted the Ukrainian sports ministry for creating obstacles in negotiating the contact, and condemned the Ukrainian government for refusing to provide background data and charts on the stadium.

"These are in violation of international construction norms and rules of the Union of European Football Association (UEFA)," the statement said.

Ukrainian Football Federation's vice president Boris Voskresensky said that if ADG was incapable of finishing the project on time, UEFA would revoke Ukraine's right to host Euro 2012. (dpa)
