Perhaps you should try some spelling variations:
sudan debt » sudan west
sudan der » suden der, sudan das, sudan die
amin hong » min hong, among hong, tin hong
hong guan » thong guan, cheng guan, hong tan
yang xi » yang yi, yang jui
yang ka » yang fan, yang yao
ad 3 » a 3, ad _, d 3

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: ((((yang xi) or (yang ka))) or (yang di))ad 3 ((sudan debt) OR (sudan der)) a amin hong guan ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((((yang xi) OR (yang ka))) OR (yang di))ad 3 ((sudan debt) OR (sudan der)) a amin hong guan ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((yang xi) or (yang ka))) or (yang di))ad 3 ((sudan debt) OR (sudan der)) a amin hong guan ;*".
