China’s massive underground tunnels that link its southern cities to the north are helping Beijing avoid U,S.

trade sanctions that could hit the world’s second-largest economy.

The tunnels provide a crucial lifeline for millions of people living in the southernmost regions of China, including Xinjiang, where the Dalai Lama lives.

The tunnel system stretches about 1,100 kilometers (800 miles) beneath the earth and is one of the world\’s longest.

It was built to facilitate trade between China and the United States, but has become a target of U.N. sanctions that have already resulted in the cancellation of $1.4 billion in Chinese trade deals with the United Kingdom and Australia.

In the past, China has sought to avoid U.,S.

restrictions on exports and imports.

But last year, as the U.K. and Australia eased restrictions on China’s exports to the U., Beijing said it would cut back on its exports to U.A.E. and U.J.A., two U.M.B.H. zones in which Chinese workers have lived for decades.

The U.P. has since threatened to cut off Chinese exports to its northern neighbor if China does not agree to stop restricting trade.

A U.T.O. spokesperson, speaking on condition of anonymity, said the tunnels have ”finally opened.”

In Beijing, the tunnels are often lined with bamboo and green trees.

They are often used for shopping, with tourists visiting the area from afar, or to pass the time while they work.

China’s economy is estimated at $2.6 trillion.

It exports $6.4 trillion in goods and services, mainly to the United U.B., which is headquartered in Beijing.

It imports $1 trillion in services, primarily from Australia, U.H., Canada and other countries.

U.S.-China trade has been a source of tension since President Donald Trump took office.

While China\’s leaders have expressed regret that the U,P.

and other nations have imposed restrictions on their economy, China is unlikely to change course.

”The tunnels provide an important lifeline,” said David Siegel, an associate professor at the China Institute of International Studies at The University of Sydney, a leading U.C.L.A.-accredited university.

”There\’s a lot of resentment among China\’ll working class people, and that resentment has been growing.”
