South Korea ranks 10th among 16 countries and the EU in this year's annual Country Ratings Poll for the BBC World Service.   More than 26,000 people were surveyed in 25 countries for the poll. Respondents were asked to rate 16 countries and the EU on "whether their influence in the world was mainly positive or mainly negative."   South Korea came out marginally on the side of the angels with a 36 percent positive rating and 31 percent negative rating. Positive views of the country dropped 1 percentage point from 2012 and negative ones rose 4 percentage points.   But in overall rankings, South Korea still jumped two notches.   Chung Won-chil at the East Asia Institute said the country's ranking was positively affected by the Korean Wave, especially the popularity of rapper Psy's "Gangnam Style," despite the North Korean threat.   Germany was the most positively rated country but Germans rated South Korea most negatively, with 65 percent against a mere 17 percent positive votes.   Germans viewed Asian countries in general negatively, with only 13 percent and 28 percent having a friendly view of China and Japan.   South Korea was also seen as a bad influence by France (47 percent), Mexico (45 percent), Canada (41 percent), the U.K. (40 percent), and Turkey (40 percent). But it found approval in Indonesia (58 percent), Ghana (55 percent), the U.S. (47 percent), Australia (45 percent), China (44 percent) and Spain (43 percent).   South Korea, China and Japan also did not think very highly of each other. Only 19 percent of the Japanese saw South Korea positively, down 15 percentage points.   A mere 21 percent of South Koreans and 17 percent of Chinese liked Japan, while only 23 percent of Koreans and 5 percent of the Japanese had positive views of China.   Germany scored 59 percent positive ratings and just 15 percent negative. Next came Canada (55 : 13) and the U.K. (55 : 18).   Japan slid from top last year to fourth place this year. China came eighth. Iran was the most disliked country in 17th place, followed by Pakistan (16th) and North Korea (15th).
