Broadband :: Change Route Of Connecting An IP?

I play a game called Unreal tournament 2k4 in online. I am from Bangladesh a small country from south asia. I used to get 150 ping in a Japanese server. But 2 weeks ago my ping suddenly rise. Now its around 268-320 in same server. But i have 160 ping in another Japanese server. So i used trace-route option from avast IS to check the route of my connection.I found out that the server i am having high ping connects through Italy then to Japanese server. But the server i have low ping goes to Singapore then to Japan.My question is can i change the route of my connection so my first server doesn't take the route of Italy?
