As an LCA I was in the right seat and training a new B787 type aircraft Captain in the left seat. We had landed from on Runway  XXR in ZZZ and taxied to gate. Upon approaching the gate there was a marshaller and a wing walker on both sides. They were all giving us the all clear signal and marshalling us in to the gate. Gate X is a challenging gate because close proximity to other aircraft. We noticed tractors; baggage carts; containers; and container trailers all parked in the transgression zone on both sides of the entry path. We stopped the aircraft and attempted to contact Operations. As we waited the wing walker; especially on aircraft right; seemed to be frustrated and continued to try to get us to move forward. I witnessed a baggage tractor drive up and just push some of the baggage carts; not even taking time to hook up and pull them. Operations radioed back and told us they would call the ramp. A pickup truck showed up; presumably with a ramp supervisor. The person got out and started directing the removal of the equipment from the path of the aircraft. It was extremely hard for us to see the lines marking the transgression zone and we wanted to be able to rely on the ramp team; but it was more than obvious due to our experience with our aircraft; taxi training; and taxi experience; that we weren't safe to proceed. Finally they cleared all of the obstructions except for one container cart. Once that was cleared and could confirm that the transgression area was clear; we taxied in. What was most disturbing about this whole situation was the continued all clear signal from the wing walkers and the signal to continue the taxi from the marshaller.
B787 Captain reported a ground conflict with ramp vehicles during taxi in and cited concerns with the ramp marshaller instructions to continue taxi without properly clearing the transgression zone area before continuing their taxi in.
