Narrative:

My aircraft was pointed east in taxiway bravo holding short of taxiway uniform at lax. It was night time. While parked behind the hold line I observed what appeared to be a B777 crossing runway 25R headed north on taxiway uniform. Lax ground queried us to ensure we were holding short of taxiway uniform. My first officer ensured him we were holding short of uniform. As the B777 began to cross north of 25R we noted his left wing would not appear to clear my aircraft. I made a call on lax ground frequency exclaiming something to the effect 'B777 stop; stop crossing rw 25R headed north on taxiway uniform.' while attempting to verbally stop the B777 I also turned on my taxi; turnoff and wing takeoff lights. The B777 stopped with his nose onto or very close to taxiway bravo. Had the B777 aircraft continued straight or turned east onto bravo taxiway it appeared that his wing would have impacted our aircraft. In looking at the lax airport pages I did not see any restrictions on wing length on taxiway uniform while aircraft are holding short on bravo. I would suggest that an ops analysis be made ensuring adequate clearance at the intersection of taxiways uniform and bravo at lax. If warranted I suggest the hold line on bravo be moved back to ensure adequate clearance. I also suggest that intersection be designated a hotspot with a ball note.
