Indonesia said on Tuesday it was pinning its hopes on U.S. Defense Secretary Jim Mattis to help ease American limitations on ties with an elite Indonesian special forces unit, imposed over human rights abuses in the 1990s. Mattis told reporters a major component of discussion with Indonesian Defense Minister Ryamizard Ryacudu was broadening education and training with counterterror units in the country, including the special operations group known as Kopassus, which has long been barred from working closely with US forces because of past human-rights abuses. Mattis is making a short tour in Asia that will also take him to Vietnam, days after he described China as using “predatory economics’’ to extend control over its smaller neighbors. He will also travel to the Pacific Command in Hawaii, where he meets South Korea’s defense minister.
