The debt crisis in Greece has gained the world’s attention. However, some activists say many other countries are building up dangerous levels of debt. They say private investors are lending money to those countries without enough rules or legal safeguards.
    European officials avoided one financial crisis recently. Greece reached a deal with other European countries to meet its short-term loan obligations last week. The Greek government is expected to begin negotiations on a three-year plan to deal with its international debt. Debt activists say there is the possibility of a debt crisis in other areas, especially in the developing world. A British group called the Jubilee Debt Campaign studies debt owed by countries around the world. The group says 22 countries are currently in a debt crisis. Many more face a high risk of financial problems in their public or private sectors.
