China

The U.S. and China are the two largest economies in the world — and interdependent in a host of ways. But as leaders from both countries start annual high-level talks in Beijing, disagreements over how China does business are creating some trust issues in the relationship.

"You might want to think of the US China relationship as kind of like an arranged marriage," says Arthur Kroeber, a Beijing-based economist and author of China's Economy: What You Need to Know.

A 5,000-year-old brewery has been unearthed in China.

Archaeologists uncovered ancient "beer-making tool kits" in underground rooms built between 3400 and 2900 B.C. Discovered at a dig site in the Central Plain of China, the kits included funnels, pots and specialized jugs. The shapes of the objects suggest they could be used for brewing, filtration and storage.

It's the oldest beer-making facility ever discovered in China — and the evidence indicates that these early brewers were already using specialized tools and advanced beer-making techniques.

Last October, China ended its 35-year-old policy of restricting most urban families to one child. Commonly referred to as the "one-child" policy, the restrictions were actually a collection of rules that governed how many children married couples could have.

"The basic idea was to encourage everybody, by coercion if necessary, to keep to ... one child," journalist Mei Fong tells Fresh Air's Terry Gross.

Another sharp fall forced China's stock market to close less than 30 minutes after trading began Thursday, setting up another rough day for investors. In the first half-hour of U.S. trading, the Dow Jones index fell by more than 1.2 percent — and that was after clawing back 90 points of an initial drop.

After trading in China was halted automatically the second time this week, officials said Thursday that they're suspending the "circuit breaker" that shuts down the market if a key index falls by 7 percent.

China's stock markets stumbled badly on the first day of trading in 2016, with a 7 percent plunge forcing a market shutdown. The trigger mechanism that cut the day short in Shanghai and Shenzhen was created in response to last year's market crash, which brought trillions in losses.
