Giant flower farms in the Yunnan province in China cultivate and grow carnations, roses and lilies in huge greenhouses, which are then exported.
The Americans are worried the effect cheaper imports will have on their own domestic sales.
Chinese workers earn $25 a month for their labour and this includes de-thorning the roses by hand and wrapping them for shipment.
Exports are due to start later this month to the USA and the Netherlands . The growers in China are now suppliers to markets from Singapore to Moscow .
Li Gang, deputy chief of the Flower Association, a provincial government agency said, "Our plan is to become the biggest flower producer and exporter in Asia in 10 to 15 years."
The central government of China is spending $200 billion a year to build roads, bridges, airports, and phone systems to ensure that inland regions of China can communicate with the outside world for the flower exports.
Free refrigerated trucks are being made available to transport the flowers to prevent them from wilting.
However governments in the West are complaining that the Chinese growers do not pay royalties when internationally registered flowers are grown. This could lead to a restriction on the amount of flowers the Chinese are allowed to export. This issue has already interfered with a new breed of thorn-less roses being transferred to China.
What many fear in the west is that the Chinese may start over producing and ship such a large number of flowers that wholesale prices could fall.
