Fiame Naomi Mataafa, the opposition leader set to become Samoa's first female prime minister after a weeks-long political impasse, said she intended to maintain good relations with China but she had more pressing needs to address.
The proposed construction of the wharf in Vaiusu Bay has been a divisive issue in Samoa, playing a part in April elections where long-serving leader Tuilaepa Sailele Malielegaoi lost his parliamentary majority. read more
The project has also threatened to spark a waterfront contest in the Pacific as the United States and its allies respond to China's growing regional influence.
"Samoa is a small country. Our seaports and our airports cater for our needs," Fiame told Reuters on the phone from Samoa's capital of Apia.
"It's very difficult to imagine that we would need the scale that's being proposed under this particular project when there are more pressing projects that the government needs to give priority to."
Her stance marks a decisive break from Tuilaepa, whom Beijing has counted on as a close ally of China over his two-decades as leader.
China is the single largest creditor in Samoa, a country of 200,000 people, accounting for about 40%, or some $160 million, of the small nation's external debts.
Tuilaepa has previously said Pacific countries only have themselves to blame if they fall into unsustainable debt.
He has frequently described the Vaiusu wharf in parliament as a "China-funded project" that would create much-needed jobs and increase trade and tourism. Port designs and funding arrangements have not been disclosed.
The Chinese foreign ministry and Tuilaepa's office did not respond to questions.
Fiame's government could be formed as early as Friday, although legal challenges may cause delays.
The Vaiusu port site is located close to the country's main Apia port in Matautu, which has recently been expanded with financial aid from Japan.
However, China's investment has drawn greater interest, and criticism.
Facilities that could be turned into a military asset in hostile times pose a challenge to the United States and its regional allies, which have dominated international influence in the world's largest ocean since 1945.
