Does anybody know the name of this movie based on this scene?

I watched this movie a long time ago but I don't remember the name of it. All I remember is that it was a movie about Asian people and White people and that the movie was very violent and bloody.

In one scene, a white man with a mustache dressed in a suit starts to kill a bunch of Asians in a store or a house. When he is done killing them, he turns to look at an Asian woman dressed in a long pink kimono. The woman says something like "You're not going to hurt me, are you?" And the man says something like "Don't worry, I don't hurt or kill pretty women like you." Then the woman says "Thank you, sir." Suddenly she turns around and a guy gives the man another weapon and as the woman is walking away from the man, the man suddenly points his gun at her and shoots her from behind. She falls to the floor and dies.

This is the only scene I remember from the movie. I watched it in Mexico when it first came out and I remember that it was before 2010. If anybody knows the name of this movie please let me know!
