Place 3 tablespoons of the tea leaves into a small bowl and add boiling water; steep six minutes. Strain the tea and discard used tea leaves. Cool to room temperature and hold.
In a spice grinder or with mortar and pestle, finely grind the remaining tea leaves to dust. Transfer to a medium stainless or glass bowl, along with soy sauce, fish sauce, sriracha, oil, garlic and pepper. Mix well. Pour in reserved cooled tea and mix.
Cut off tips of chicken wings. Cut wings into two parts at joint, place in resealable plastic bag and pour tea-based marinade over wings. Seal well and mix to coat completely. Refrigerate overnight before preparing, turning bag every 12 hours.
To cook, remove wings from refrigerator and bring to room temperature. Remove wings from bag and discard marinade. Drain very well.
Preheat grill to medium. Grill wings until cooked through on both sides and juices are running clear, about six to eight minutes per side.
Serve Hot Green Dipping Sauce on the side.
