Heat oven to 400°F. Place chicken wings in one layer on a nonstick baking sheet; bake for 20 minutes. Drain liquid, turn wings over and bake for 25 minutes more or until lightly browned and cooked through.
While wings are cooking, melt butter in a skillet. Add green onions, ginger and garlic; sauté for 3 minutes. Add sweet & sour dipping sauce, brown sugar and soy sauce; stir until sugar has dissolved and sauce is heated through. Remove wings from oven and place in a bowl. Pour sauce over wings and toss to coat. Serve hot.
