The Korean peninsula made headline news all over the world this week. South Korea's president Park Geun-hye, now former president, was sacked and will most likely face corruption charges. North Korea's muscle flexing is testing the new US administration as well as its neighbour China, believed to be an ally, and challenging Malaysia over the assassination of Kim Jong-nam, the North Korean leader's half-brother. In this week's Spotlight on Asia, RFI's Rosslyn Hyams speaks to Jonthan Holslag, specialist on security issues in East Asia, about the current brinkmanship in the region. He warns, "we have to be careful that this tiny little power on the doorstep of China doesn't become the Serbia of the 21st century."
