On his last day in Downing Street, David Cameron said one of his proudest achievements was to honour the commitment to spend 0.7% of gross national income on international aid. It was partly an attempt to stake out his legacy and partly a pitch to his successor, Theresa May, to stick to, what remains, a Conservative manifesto pledge.

Over the past two decades, Russia's efforts to regain its Soviet-era influence in Africa have achieved little success because "times have changed significantly, for example, a new economic and political environment, new emerging challenges, new competitive conditions and new bases for cooperation," according to Nataliya Zaiser, a Public Policy Advisor at Squire Patton Boggs Moscow office. 

The Chinese government has spent billions in recent years to subsidize artistic enterprises, with an eye toward wielding "soft power" beyond its borders. It hasn't been notably successful. But China's video game industry -- as of last year, the world's biggest -- is on the verge of becoming one of its most valuable cultural exports. It just might succeed where so much Chinese entertainment has failed in the past.

Chinese influence in Australia is growing across a broad front, from political donations to Confucius Institute teachings in primary schools and university institutes funded from Beijing. These continuing efforts to spread soft power have found a new friend, with an announcement that content from Chinese newspapers and wires will run in Australian media and on the Sky TV cable television channel.

In recent weeks, business deals between Australian and Chinese media groups have raised concerns over potential Chinese government influence in the Australian press. But according to a report in the Australian Financial Review, the media is not the only institution that has recently received Chinese government money as part of a soft power push by Beijing.

Turkish President Recep Tayyip Erdogan, who has become a leader nobody in the West is eager to host, has decided to steer toward countries with leaders he thinks might understand him: Uganda, Kenya and Somalia. [...] It's become a tradition for Erdogan to begin his foreign travels with much fanfare and overdone public relations campaigns.

Joseph Nye has been the preeminent thought leader on the issue of power dynamics and relationships connecting global actors. [...] What is the future of this American century? My guess is that among the range of possible futures, ones in which a new challenger such as Europe, Russia, India, Brazil or China surpasses the United States and precipitates the end of the American centrality to the global balance of power are not impossible, but not very likely.

The World Humanitarian Summit (WHS) may well be a signature initiative of UN Secretary General Ban Ki-moon, designed to create for himself a dynamic, if not dubious, humanitarian legacy, but it could hardly have been more heartily welcomed than in Turkey, the country where the 2016 WHS will take place later this month.
