To prepare the sauce, in a small bowl, soak the fermented black beans in water for 5 minutes. Drain and mince.
Place a saucepan over medium-high heat. Add 1 tablespoon of the oil with the garlic, ginger, and green onion and sauté for 20 to 30 seconds, until barely light golden brown. Add the remaining 1 tablespoon oil, then add the black beans and cook for 2 minutes, or until the seasonings are aromatic. Add the wine and bring to a boil for 2 to 3 minutes. Add the clam juice and bring to a boil for 2 to 3 minutes. Add the demi-glace and bring to a boil for 2 to 3 minutes. Whisk in the sugar and oyster sauce and blend well. Taste and adjust the seasoning with sugar if necessary. Add the butter and mix well. Decrease the heat to achieve a bare simmer and keep the sauce warm.
Preheat the oven to 325 degrees F. Combine the char siu sauce and hoisin sauce in a bowl and mix well. Coat the pork chops with the marinade.
Heat a large ovenproof sauté pan over high heat. Add the oil and when the oil is hot, add the chops and sear for 3 to 4 minutes, until caramelized and brown. Turn and sear the other side for 3 to 4 minutes, until caramelized and brown (do not allow to blacken). Remove the pan from the heat and place in the oven to finish cooking the chops, about 10 minutes, or until an instant-read thermometer registers 140F .
To prepare the vegetables, place a wok over high heat. Add the oil, garlic, and ginger and stir-fry for 20 to 30 seconds, until barely light golden brown. Add the red bell pepper, yellow bell pepper, and beans and cook for 3 to 4 minutes, until cooked but still crunchy.
To serve, spoon a pool of sauce onto each of 4 plates. Divide the vegetables among the plates and place a pork chop on top of each pile of vegetables. Garnish with the green onion and serve immediately.
