 Operation Sumber 4, 2019, is the culmination of an Interpol Capacity Building initiative impacting the Tennyson countries. This was conducted in the framework of an externally founded project to sponsor it by the Government of Canada. Since 2015, Operation Sumbered has been growing gradually from 15 spots to be managed at that time at the borders to the 90 spots that today are part of this operation. That depicts clearly the capacity building action that Interpol has been putting in place in the ASEAN region, enhancing the capability of border management and integrating all the services to promote and produce more sound and sustainable border management control. This has entailed three different dimensions, individual set of skills as well as institutional develop in terms of standard operational procedures and institutionalization of processes and infrastructure development. All this allowed all the Tennyson countries today to reach this point where integration and border management is a fact.
