Preheat the oven to 300°F (150°C). Line a baking sheet with foil.
Season the ribs with salt and Chinese five-spice powder, then place them on the baking sheet.
Cover tightly with foil and bake for 2.5 to 3 hours until tender.
In a saucepan, combine hoisin sauce, honey, soy sauce, rice vinegar, garlic, and ginger. Simmer until thickened.
Brush the ribs generously with the glaze and broil for 5 minutes until caramelized.
Brush with extra glaze before serving and garnish with chopped green onions and sesame seeds.
