In a small bowl, combine the first five ingredients. Place cornstarch in a large bowl. Add chicken in batches; tossing to coat. In a large skillet, heat oil over medium-high heat. Add chicken; cook and deep fry until no longer pink, 8-10 minutes. Remove and keep warm.

Stir soy sauce mixture and add to pan. Bring to a boil; cook and stir 1-2 minutes or until sauce is thickened. Return chicken to pan; heat through.

Serve hot.
