In a slow cooker, combine soy sauce, brown sugar, rice vinegar, sesame oil, garlic, ginger, and red pepper flakes. Stir until well mixed.
Add the chicken thighs to the slow cooker, ensuring they are well coated with the sauce. Pour in the chicken broth.
Cover and cook on low for 6-7 hours or on high for 3-4 hours, until the chicken is tender and easily shredded.
Once cooked, shred the chicken using two forks and stir it back into the sauce.
Serve the shredded chicken over cooked jasmine rice. Top with shredded carrots, sliced green onions, and sesame seeds.
