I would use whichever Asian piece fits the tv as a tv console. Then purchas or have custom built...two large column bookcases one on each side of the credenza...to reach to the soffit. Install glass shelves in the bookcases. Get rid of the cream sofa...I can't tell what is opposite it, but, it is white. It looks like you have too much large furniture all fighting to have their style be "the winner" and nothing meshes. Use the lower asian cabinet under the window...then a cluster of the traditional style chairs grouped for conversation. 2 and 2 facing each other perpendicular to the window. The small tables could be between the chairs. They could be very similar to the armchair that is in the picture, not matching...but the wood frames all the same color and the upholstery the same. Then repeat the upholstery in decorative pillows on the sofa. Using the armchairs in the traditional area, gives you lots of flexibility as you can easily move them over facing the sofa when you wish to create a larger conversational grouping, or facing the tv when there is something special you want to watch. Get rid of the curio cabinet and the round glass table as they are too much in contrast with the leather sofa. Paint the smaller tables in a bright color to add a pop of color...repeating the color in pillows on the sofa. (I see an orangey colored throw on the sofa...that would be a nice accent color) You could add lights in the bookcase columns for interest. Then, look for an unusual lamp or chandelier to hang in the corner behind the curve of the sofa. I would hang floor to ceiling draperies with the large grommets in the top to repeat the medalian on the asian pieces. Add a wide band of the accent color to the bottom of the draperies. Place 2 unique wall sconces on each side of the wall unit...something that draws the 2 styles together, maybe with hints of the accent color. A large piece of artwork, which includesvthe accent color, to be hung over the sofa. It would be fun to have a frame in an ornate traditional style, but painted to match the asian pieces. Thanks for the opportunity it was fun!

There is contrast between the traditional furniture and the focal point of the floor which pops, draws attention. I would recover the sofas in cream colored soft fabric - suede. I would leave the curtains grey, and put down a large neutral area rug. The edges of the room would show the pattern of the floor. I would color the wall and add texture to it, but not too dark as the room will appear smaller. Add a picture and put a nice plant holder, large vase in the left corner of the room - an oriental-style vase. Or, a cream-stripe fabric on the sofas. You could go soft or bold in this room - depending on your taste.

Love the armless sofa-bench! Try using it in the center as a "cross-linking" piece between the sofa and chairs. That way people can sit on both sides of it, conversing with the sofa people and the chair people. Put the chairs where it is and use the side table from the left of the pic, or the one with flowers, between them. You'll need one huge rug to anchor the space or two smaller, and very similar ones, to put on either side of the blue sofa-bench. The other two side tables are too tall and too short for your seating pieces, so ditch them. Use your coffee table between the sofa and armless sofa (18" away from each of them.) Here's a chart for judging table and lamp heights as you'll need to work on that for balance. Please try this arrangement, and post by commenting and using the Attach Images button to add pix of the update. We'll tweak it on out from there.

I think all white will be a very nice scheme and the differences in the white will just add subtle difference. In the above pic the walls are more white than the table, but mixing with the light tan colours and greyish tones makes this gradient of whitish tones work well.This room is all white as well with the furniture and walls, but adding the punch of the other colours masks if the whites are slightly different as the bright colours become the focus. The walls in the pic below 'read' a very pale grey so that would be an option, just ensure that it is a whitish-grey and not muddy or warm. I would choose the sofa colour as your main colour and accents to match from there.
