Gauge field configurations appropriate for the infrared region of QCD are proposed in a submanifold of su(3). Some properties of the submanifold are presented. Using the usual action for QCD, in the absense of quarks, confinement of these configurations is realized as in the London theory of Meissner effect. Choosing a representation for the monopole field strength, a string action corresponding to the effective gauge theory action in the infrared region, is obtained. This confining string action contains the Nambu-Goto term, extrinsic curvature action and the Euler characteristic of the string world sheet.
