US lawmakers are considering doubling funding for democracy and human rights promotion in North Korea to $4 million. The measure under consideration also would ask the US government to look for ways to help North Korean refugees to settle in the United States. The House of Representatives' Foreign Affairs Committee plans to debate the bill next Wednesday. The new funding would boost aid for groups seeking to improve rights in North Korea. It also would provide grants for more US-financed radio broadcasts into the isolated nation. The bill also would elevate the US special envoy for North Korean human rights to a full-time ambassadorial position.
