Heat the canola oil in a large skillet or a wok until small puffs of smoke begin to appear. Add the onion and garlic and stir-fry over high heat until the onion is just crisp-tender, about 1 minute. Add the eggplant and stir-fry until browned in spots and just tender, about 5 minutes. Add the Chinese cooking wine and cook until nearly evaporated, about 1 minute. Add the Vietnamese Stir-fry Sauce, water, coconut milk and chili paste. Cook over high heat, stirring occasionally, until the eggplant is very tender and the sauce is slightly reduced, about 5 minutes longer. Add the scallions and cook for 30 seconds. Serve the eggplant hot.
