China's cultural scene has certainly flourished in recent years from art, to music and, of course, museums. Curator Cheng Guoqin says part of the reason the government supports the opening of new museums is that it improves the country's image. "The government has realized that economic success is not enough," she says. "It realizes that soft power and the creative industries must play an important role."

Providing medical care in foreign countries is a great way to improve the U.S. image abroad. The U.S. Navy hospital ships Mercy and Comfort are prime examples of an effective soft power program. These hospital ships provide medical care to impoverished communities worldwide. The USNS Mercy is itself one of the largest trauma facilities in the United States. 

The total number of tourists in Mexico hit a record in the first half of the year, with more than 14 million foreigners touching down, almost 20 percent more compared to last year, the Tourism Department said.  The spike in visitors, especially Americans, comes after several years of stagnation in the travel sector here amid a slow global economic recovery and fears of gory cartel violence.

Soft power – using diplomacy, co-operation and the powers of attraction rather than coercion – has become a more potent force in international relations over recent decades. During the Ukrainian crisis, Germany, with its conciliatory, sanctions-focused approach, has been a leading exponent of the approach. Yet faced with what looks increasingly like the use of "hard power" by Russian soldiers on Ukrainian soil, its limits are being tested.

Hong’s new book, “The Birth of Korean Cool: How One Nation Is Conquering the World Through Pop Culture,” loosely follows South Korea’s growth from the mid-60s, when the country’s per capita G.D.P. was less than Ghana’s, to now. Today, South Korea is the 15th-largest economy in the world. From Psy’s “Gangnam Style” video to the chips that Samsung furnishes for Apple’s iPhones, the book explores the confluence of factors that make for Korea’s pop-­cultural perfect storm.

Europe's failure to stem conflicts raging just outside its borders is calling into question the EU's focus on "soft power," centered on discreet diplomacy, economic incentives and in particular Europe's own example of former enemies working together to build common prosperity.
