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.

The United States announced in 2010 that it had lifted its outright ban on U.S. military contacts with the Indonesian special forces unit, known as Kopassus, which was accused of rights abuses in East Timor as it prepared for independence.

But legal restrictions meant to ensure the U.S. military does not become entangled with rights abusers prevented contacts with Kopassus from advancing beyond preliminary levels, U.S. officials say.
