China exec probed for leaking price strategy to Rio

CANBERRA/BEIJING (Reuters) - A Chinese steel executive detained along with four Rio Tinto employees is under investigation for leaking China's "bottom line" in iron ore price negotiations, a source with knowledge of the probe said on Friday.

Tan Yixin, the head of iron ore imports for state-owned steelmaker Shougang, has been taken into custody on suspicion of "revealing China's negotiating strategy" to Anglo-Australian miner Rio Tinto Ltd, the source told Reuters, requesting anonymity.

The shock detentions have cast a shadow on relations between Beijing and Canberra, whose economies have been welded together in recent years by China's huge demand for metals and minerals.

As Australia sought to avert the diplomatic row, the China Securities Journal said Shanghai's State Security Bureau accused the three local Rio staff and senior Australian executive Stern Hu of bribing unidentified Chinese steelmakers during tense iron ore price negotiations this year.

"This seriously damaged China's economic security and interests," said the paper, which is published by the state-run Xinhua news agency. "The activities of Stern Hu and the others violated Chinese law as well as international business morality."

Asked if negotiating strategy meant iron ore prices, the Reuters source said: "Yes, China's bottom line."

Shougang officials could not immediately be reached for comment.

China's ambassador to Australia was summoned to the Foreign Ministry late on Thursday to discuss what local newspapers called a fast-escalating crisis.
