Definition of "Dongding"

At present, America has committed itself to an "all-round responsibility" policy along our coast. It seems to me that the Americans will only feel comfortable if they take complete responsibility for Jinmen and Mazu, or even for such small islands as Dadan, Erdan, and Dongding [small islands within the Jinmen archipelago]. America has fallen into our noose. Thereby, America's neck is hanging in China's iron noose. Although Taiwan is [for America] another noose, it is a bit farther from [the mainland]. America is now moving its head closer to us, since it wants to take responsibility for Jinmen and other islands. Someday we will kick America, and it cannot run away, because it is tied up by our noose.
