Denise Mauzerall arrived in Beijing this year at a time that was both horrifying and illuminating. The capital was facing some of its worst pollution in recent memory, and Mauzerall, a Princeton environmental engineering professor, was passing through on her way to a university forum on the future of cities.

"I took the fast train from Beijing to Shanghai, and looking out the window for large sections of that trip, you couldn't see more than 20 feet," Mauzerall recalled.

To Mauzerall, the lesson was surprising and inescapable.

Shanghai did something last fall that few other cities on the planet could have even considered. It opened two massive art museums right across the river from one another on the same day.

The grand openings put an exclamation point on China's staggering museum building boom. In recent years, about 100 museums have opened annually here, peaking at nearly 400 in 2011, according to the Chinese Society of Museums.

Africa is facing a growing epidemic: the slaughter of rhinos.

So far this year, South Africa has lost more than 290 rhinos — an average of at least two a day. That puts the country on track to set yet another record after poachers killed 668 rhinos in 2012.

The past couple of months have been unsettling ones for meat eaters in Shanghai.

In March, more than 16,000 dead pigs showed up in a stretch of the Huangpu River — a main source of the city's drinking water.

General Motors has been the American car company in China. Even when GM was in bankruptcy, the Chinese continued to view Buick as a high-status, luxury brand.

But now Ford, an also-ran in the market for years, is making a push to change all that. Last year, Ford's sales were up more than 30 percent in China, and the Ford Focus was the best-selling car in both the world and China.

This week, North Korea closed off the last avenue of economic cooperation with its rival, South Korea. Pyongyang says the closing of Kaesong — a joint North-South industrial complex — is temporary.

But the move is a big symbolic blow on the Korean peninsula and a potential disaster for some of the South Korean businesses that have invested there.

Nearly two decades ago, a North Korean official threatened to turn Seoul into a "Sea of Fire." South Koreans responded by cleaning out the shelves of supermarkets and preparing for an attack that never came.

On Tuesday, North Korea urged tourists and foreign companies to leave South Korea for their own safety, saying the two countries are on the eve of a nuclear war.

STEVE INSKEEP, HOST:

Not long ago, it seemed that China was on its way to owning the solar energy business. China was making solar panels far more cheaply than U.S. companies. Now things look a little more complicated. China's Suntech was forced into bankruptcy yesterday. It's one of the world's largest solar panel makers. Suntech has to reorganize after defaulting on a bond payment of more than half-a-billion dollars.

Its falls reflects problems in China's approach to the global solar industry. NPR's Frank Langfitt reports.

More than a week has passed since thousands of dead pigs were first discovered floating in a river in Shanghai, but authorities have yet to explain fully where the pigs came from or why they died.

Fourteen of the pigs had tags in their ears identifying them as coming from Jiaxing city, in neighboring Zhejiang province. Getting to the bottom of the pig story, though, is tough. A visit to Zhulin village, where most everyone raises pigs, was greeted by serial denials.
