Place beans in small bowl; cover with warm water. Stir beans about 2 minutes to remove excess salt. Remove beans from water; drain well. Cut radishes diagonally into 1/4-inch slices. Cut green onions diagonally into 2-inch pieces. Mix cornstarch, 2 tablespoons water, the sugar and soy sauce.
Discard any broken or open clams; place remaining clams in large bowl. Mix 3 cups water and the vinegar; pour over clams. Let stand 30 minutes. Scrub clams under running cold water.
Place clams in steamer with 1/2 cup boiling water. (If steamer is not available, place clams in Dutch oven. Add 1 inch boiling water and cover tightly.) Steam clams 5 to 6 minutes or until clams open at least 1 inch; remove clams as they open. (Discard clams that do not open.) Strain clam liquid through double-thickness cheesecloth; reserve 1/2 cup. Remove clams from shells; cut each clam into halves. Keep clams warm.
Heat wok until very hot. Add vegetable oil; tilt wok to coat side. Add beans, garlic and gingerroot; stir-fry 10 seconds. Add radishes and reserved liquid; reduce heat to medium. Cover and cook 5 minutes. Stir in cornstarch mixture; cook and stir until thickened. Add green onions and clams; stir-fry 1 minute.
