In response to the world's top three iron ore suppliers' negotiation attitude of "take it or leave it", China can both take it and leave it in different ways, experts say.

"It seems China has accepted the quarterly benchmark iron ore pricing scheme proposed by the iron ore trio," said Zhang Lin, analyst at Langesteel.com, the country's leading steel information service provider, while on the other hand, "it is increasingly finding substitutes for iron ore."

Vale, Rio Tinto and BHP Billiton, which account for nearly 70 percent of global iron ore shipments, have all announced they will shorten the duration of long-term agreements for international iron ore prices, signalling the end of the decades-old annual benchmark pricing system.

The three giants established the quarterly benchmark pricing scheme at the beginning of this month by reaching a deal with the Japanese steel industry, hiking prices nearly 100 percent.

Luo Bingsheng, vice chairman of the China Steel Association, said Wednesday the association had allowed steelmakers to buy iron ore independently since no agreement has been reached between the association and the trio.

"Although Luo said the association has not given up trying for a more acceptable price based on an annual benchmark pricing system, it has given de facto recognition to the new system with tacit consent," Zhang said.

"The price hike has almost driven Chinese steel mills, who survive on only three percent profit margins, to desperation," said Zhou Xizeng, a senior analyst with CITIC Securities.

The first quarter net profit of 77 large and medium-sized steelmakers in China declined 14.31 percent from the previous quarter.

While the overall profit margin for China's steel industry in the first quarter was just 3.25 percent, lower than the average 6 percent profit margin of the country's industrial sector.
