• Flying geese development model reinforces dependence
on the USD
▪ Providing liquidity is key: If a country wants its money to be
accepted as payment in the rest of the world, it must import (rather
than export)
□ Implication: for CN's renminbi to circulate in the rest of the
world, it needs:
to rebalance its current accounts and import more
(boost domestic consumption and domestic investment
and decrease exports).

can be held as a foreign investment
