PT Freeport Indonesia, which has large copper and gold mines in Papua, already set the price for 10.64 percent stake it is to divest this year at Rp23 trillion (US$1.7 billion).
Rini, however, said the price is too high especially as the prices of the commodities produced by the U.S. company are on the decline.
Sudirman said Freeport has not given dividends to its shareholders in the past three years on shrini8king profit.
Whether the dividends would be paid or not depending on the decision in the shareholders meeting, he said.
Acquisition of the 10.64 percent stake would give the government significant voting power of 20 percent, he said.
Currently the government has 9.36 percent stake in Freeport.
Freeport is required under its contract to divest 30 percent of its shares to the government or Indonesian companies named by the government.
Divestment is to be made by phases -- 20 percent this year and the rest in 2019.
This year divestment is only 10.64 percent as the government already has 9.36 percent stake in the subsidiary of the U.S. mining giant Freeport McMoRan Copper & Gold.
