The US Food and Drug Administration has opened its first office in China as part of a global strategy to ensure the safety of imports from China.

The office is the FDA's first permanent delegation outside of the US and will be followed by two more in the Chinese cities of Shanghai and Guangzhou.

"In the past we have always been at our borders to try and catch things that were not safe or did not meet our standards," US Health and Human Services Secretary Mike Leavitt said at ceremony to mark the opening of the Beijing office on Wednesday.

"In the future our new strategy is to build safety into products at every step of the way."

The opening of the new office follows a series of safety scares over Chinese-made products.

The most recent alert has centred on the Chinese dairy products tainted with the industrial chemical melamine.

Inspections

After meetings with Chinese officials on Tuesday, Leavitt said China and the US would work on a joint initiative to use better technology for detecting contamination, demand greater corporate responsibility and increase sharing of data and information.

In the past year, China has stepped up inspections and tightened restrictions on food production and other industries, after a series of scandals.

However, analysts say it remains an uphill climb for Chinese authorities to regulate countless small and illegally run manufacturing operations.

Shao Mingli, head of China's country's food and drug administration, said the opening of the FDA office  was a "very clear signal to the whole world."

"As food and drug regulatory agencies, our first priority is to protect public health and life," Shao said at Wednesday's ceremony. "This is our top responsibility."

The FDA says it plans to open further offices in India, Latin America and Europe in coming months as it tries to step up safety monitoring of more than $2 trillion worth of goods imported into the US every year.
