American Samoa's member of the US Congress has asked the US Department of Commerce to open an anti-dumping investigation regarding canned tuna imported from Thailand.
Faleomavaega Eni Hunkin says Thailand has surged in the marketplace and now provides nearly 30 percent of the US market.
He says Thailand is the leader in supplying tuna to the US and the low cost of labour, at about 75 cents an hour, provides Thailand with a trade advantage.
The Congressman pointed out that Thai Union, which owns Chicken of the Sea, has also evolved to be one of the world's leading producers and exporters of canned tuna in the world.
Thai Union has previously been found guilty of dumping shrimp in the US and the Congressman has concerns this also may be the same with canned tuna.
