The United States and allies have also accused Iran of developing nuclear weapons but Teheran says its atomic program is for peaceful purposes.
However, Iran is defying UN demands that it stop uranium enrichment, a technology that could be used to make nuclear arms.
UN Security Council sanctions block the sale to Iran of equipment and technology related to nuclear activities and also of so-called dual-use items, which can have either a military or civilian purpose.
'We look to China to act responsibly and restrict conventional arms sales that promote instability and violate international norms,' Mr Shinn said.
Similarly, he said, the Pentagon 'still observe Chinese firms and individuals transferring a wide variety of weapons-related materials and technologies to customers around the world' - including to Myanmar, Zimbabwe, Cuba, Sudan and Syria.
In April, a ship belonging to a Chinese state-owned shipping firm was forced to abandon plans to deliver a shipment of arms to Zimbabwe amid fears they could be used to crack down on opposition supporters.
China is a major supporter of beleaguered Zimbabwean leader Robert Mugabe.
Mr Shinn also said that the United States was 'troubled' by China's lack of openness and transparency in military affairs.
'This opacity raises questions as to China's true intentions and compels outside observers to compare China's behavior and capabilities against its declaratory policies,' he said.
Mr Shinn said the United States looked forward to China's upcoming submission of its defense expenditures to the United Nations, saying it had so far significantly underreported its military budget.
China's announced defence budget for 2007 was US$45 billion (S$61.4 billion) and US$58 billion in 2008 but the Pentagon said it did not include expenditures for big items such as foreign acquisitions, expenses for strategic forces and military-related research and development.
The Pentagon estimates China's total military expenditures in 2007 to be between US$97 billion and US$139 billion. -- AFP
