Haven't try with Chineese but I had similar problems with Turkish data.The code below works well for me. You can find detailed info here . Hope this helps.

Response.Clear();
Response.AddHeader("content-disposition","attachment;filename=Test.xls");   
Response.ContentType = "application/ms-excel";
Response.ContentEncoding = System.Text.Encoding.Unicode;
Response.BinaryWrite(System.Text.Encoding.Unicode.GetPreamble());

System.IO.StringWriter sw = new System.IO.StringWriter();
System.Web.UI.HtmlTextWriter hw = new HtmlTextWriter(sw);

FormView1.RenderControl(hw);

Response.Write(sw.ToString());
Response.End();
