Rinse the rice under cold water until the water runs clear. In a medium pot, combine the rice and 2 1/2 cups of the water and bring to a boil over high heat.
Once boiling, reduce heat to low, cover the pot partially (leave about 1/2 inch opening) and simmer until the rice is cooked through; set aside. (If cooking rice ahead, do so now.)
In a small bowl, whisk together the soy sauce, lemon juice and the remaining 1/4 cup water; taste and adjust if needed, then set aside.
Heat 2 tablespoons of olive oil in a large saucepan over medium heat. Add the chicken strips and sauté until cooked through, about 5–7 minutes.
Pour in the soy-lemon mixture and add the baby corn. Bring to a simmer and cook for 15 minutes. Remove the chicken and corn from the pan into separate bowls, leaving the sauce in the pan.
Add 2 more tablespoons of olive oil to the same saucepan and heat until shimmering. Return the cooked chicken to the pan and cook until lightly golden; season with 1/4 teaspoon salt and the ground pepper. Transfer the chicken to a bowl.
Add the remaining 1 tablespoon olive oil to the pan, then pour in the reserved soy-lemon sauce. Cook for 3–5 minutes until it thickens slightly.
Stir the cooked rice into the sauce until evenly coated and browned. Push the rice to one side of the pan.
Place the chicken on the other side of the pan and arrange the baby corn on top. Turn off the heat.
Add the halved cherry tomatoes in one corner of the pan, sprinkle with the remaining 1/4 teaspoon salt if desired, and scatter the chopped chives over the dish. Serve warm.
