Early this morning, Rio Tinto (NYSE: RTP) found itself facing new allegations in the arrest of some of its employees in China. RTP is accused of overcharging Chinese steel mills by $100 million during the past six years, and the latest accusations cover the sale of iron ore.

To catch you up on the situation between RTP and the Chinese government, back in early July, RTP was accused of bribing officials and four of its employees were detained by authorities in Shanghai on suspicion of stealing state secrets. The allegations contended that the four employees bribed executives from 16 of China's major steel mills in order to obtain industry information.

Aluminum giant Alcoa (NYSE:AA) announced on Feb. 12 that it was selling its holdings of iron ore company Rio Tinto (NYSE:RTP)to Chinalco for about $1 billion, nearly $700 million more than the current value of the holdings. And speculation has begun to surface that Chinalco will make a play for Alcoa, one of the world's largest producers of aluminum.

Big China metals and mining firm Chinalco is putting over $19 billion into Rio Tinto (NYSE: RTP) which is in many of the same businesses. According to MarketWatch, "The investment by the state-owned company, known as Chinalco, would be the largest-ever foreign corporate investment by a Chinese company."

About $1 billion of the cash will be used to buy Rio Tinto shares held by Alcoa (NYSE: AA). Does the China deal put Alcoa in play? It may.
