In 2011, China objected to a growing coalition of nations that were grouping together to resist Chinese sovereignty over the South China Sea, saying that these nations could not "counterbalance and contain China as they expected." Later that year China updated its strategy to "prevent more members of the Association of Southeast Asian Nations from joining the Washington-led containment policy", through the use of "Dollar diplomacy." This has proven more effective with the poorer ASEAN countries, as these are dependent on Chinese support.
