Narrative:

After takeoff; passing 5000 ft; we were called by the flight attendants and alerted to smoke and odors coming from the business class lavatory. We elected to run the 'smoke/fumesecond officerdor' emergency checklist. As we started the checklist we were called again that the smoke was getting worse. We decided at this time to return and land immediately. We declared an emergency with ATC. We had difficulty communicating with ATC as to the nature of our emergency but they understood we needed to return to the airport. After completing the checklist the smoke started to dissipate. We contacted dispatch and told them we were returning to ZZZZ. We elected not to dump fuel and landed overweight. We asked for and received landing data which we used. We landed at 370000 pounds. On final approach we realized that there were no fire trucks so we asked tower to send the fire equipment. We landed with 30 degree flaps and maximum autobrakes. Cleared the runway and stopped the airplane and called to have it towed. The brakes on the right side overheated and the brake temperature indicator on the right side indicated between 6 and 9. The mechanic hooked up and told us that there had been a fire on the right wheels and that it had been extinguished with water. We elected to keep the passenger on the airplane and not evacuate/evacuation. We coordinated for airstairs and buses and deplaned for passenger. Callback conversation with reporter revealed the following information: the reporter had not gotten a final status report on the cause of this event. However; the initial indication was that engine or APU oil had gotten into an air conditioning pack; smoking; and filling the cabin with smoke. There was no actual fire and the engines were removed and examined at the request of the foreign government involved.
