Capt Nguyen and his men continued the rescue until dusk at about 6pm when he had to call off the rescue when it became too dark.
When he contacted his head office that night, he was told to continue with his journey to Singapore.
The Wall Street Journal (WSJ) reported that the refugees' overcrowded boat, with about 250 people on board, had sunk in the Bay of Bengal while en route from Bangladesh to Malaysia.
It reported that another nine survivors were rescued by another ship. The rest, including women and children, are believed to have drowned.
WSJ also reported that the Indian coast guard had told Capt Nguyen to drop the asylum-seekers at "the nearest port of safety", but he told TNP that he did not receive any such instruction from any agency.
Acting on instructions from his head office, Capt Nguyen decided to sail for Singapore as planned, despite ports in Myanmar, Bangladesh and India being nearer.
Capt Nguyen said that when he approached Singapore waters on Dec 9, he was told by Singapore's Maritime and Port Authority (MPA) that he could not dock in Singapore.
A MPA spokesman said in a statement last Wednesday that the MV Nosco Victory was turned away because the ship's captain could provide only "sketchy" information about the passengers it had picked up off the coast of Myanmar.
"There is no other official documentation to assist at this point, but they do not appear to be persons eligible to enter Singapore," the statement said.
After being denied entry into Singapore, Capt Nguyen tried to contact authorities in Thailand, Malaysia, Bangladesh, Myanmar and Indonesia for assistance, but his requests were turned down repeatedly.
He was surprised when told about an earlier report in WSJ about Indonesia being reportedly open to receive them.
He said he has yet to hear from any country allowing him to dock.
Despite keeping in constant contact with Northern Shipping Joint Stock Company (Nosco) head office in Hanoi on the situation on board his ship, Capt Nguyen has yet to receive any assistance from it.
When TNP contacted the Nosco head office on Monday and asked what its plans are for the ship, it declined to comment.
For now, Capt Nguyen and his crew can only look after the refugees, sometimes even helping to bathe the sickly, while hoping that some form of help reaches him soon.
With a sigh, he spoke on behalf of his crew: "We are all sad and angry when we have been pushed into this desperate predicament despite doing a good deed.
"If help does not reach us in the next few days, the refugees will all perish."
