Economic sanctions are a powerful instrument but they are only as powerful as much as the people involved care about their economy. ISIS doesn't care about economics, they care about beheading non-muslims and creating a medieval society. Taliban could have gotten rich from accepting mining companies into their country but instead they chose to fly attacks on the USA and ruin their reputation. North Korea's economy is a shadow of the south Korean one yet they won't give in and stop their nuclear program in exchange for economic help. Managing these people requires application of immediate force, aka military. Regarding China, it is building a monopoly in the hardware sector. It's already impossible to avoid China if you want to build a smartphone. The more this trend continues, the more China will exert influence with its power over that sector. For a military conflict with China, which isn't unlikely in the future, this means that anyone else would be at a disadvantage.
