In a wok or large saucepan, heat the oil over medium-high heat. Add in the chicken and cook until white on all sides. Stir in the curry paste. Add the red bell peppers and the daikon and saute for 3 minutes.
Stir in the brown sugar, fish sauce, and coconut milk. Bring just to a boil, then lower the heat and simmer for 5-7 minutes.
Sprinkle green onions and cilantro over the top just before serving. Serve over rice.
You can substitute bamboo shoots, bean sprouts, or another vegetable for the daikon.
