KIEV, May 12 – The State Property Fund will press for the return of Zaporizhia aluminum plant (ZALK) to state ownership if Russia's Rusal continues to fail to fulfill its investment liabilities, SPF head Oleksandr Riabchenko said.

"Either they fulfill their liabilities or we'll appeal to the courts, jointly with the Prosecutor General's Office, demanding the return of the company to state ownership and another investor will be found," he told the press in Kiev on Wednesday.

Riabchenko said that Rusal could sign an additional amicable agreement with Ukraine if court hearings start.
