In a bowl, combine soy sauce, rice vinegar, brown sugar, honey, ginger, garlic, and Sriracha (if using). Add the pork belly cubes and toss to coat. Marinate for at least 30 minutes or up to overnight in the refrigerator.
Whisk together cornstarch and 1 tablespoon of water to create a slurry in a small bowl
Preheat your air fryer to 400°F (200°C). Arrange the pork belly cubes in a single layer in the air fryer basket. Discard the marinade.
Air fry for 15-20 minutes, shaking the basket halfway through.
In the last 2-3 minutes of cooking, open the air fryer and carefully brush the pork belly with the cornstarch slurry. Continue cooking until the glaze thickens slightly and the pork is golden brown and crispy.
Garnish with toasted sesame seeds and chopped scallions (optional) and serve immediately with your favourite dipping sauce.
