Combine the soy sauce, molasses, sesame oil, garlic, ginger powder, fish sauce, rice wine vinegar and honey in a saucepan on medium-high heat. Bring to a slight boil, whisking or stirring constantly. Cook for 4 to 5 minutes. Set aside.
Heat a large skillet over medium-high heat and add the canola oil. Add the salmon skin-side down and cook until the skin is brown and crispy, 2 to 3 minutes. Sprinkle the salmon with salt and pepper and drizzle with a little of the sauce, then flip and cook until the salmon is about medium, another minute or two. Depending on the thickness of salmon, you may need more or less time.
Allow the salmon to rest for 3 to 5 minutes. Drizzle with more sauce before serving and sprinkle with sesame seeds.
