China's Zhoushan port, off the eastern coastal province of Zheijang, supplied a record 3.59 million tonnes of marine fuel last year, more than double the previous year's level, the state-run China Securities Journal reported on Wednesday.
Zhoushan makes up more than 30 percent of the country's total bonded bunker fuel market, the journal cited a local government official as saying.
Zhoushan's bunker volume could top 4 million tonnes this year, the report said. Bonded market refers to supplies to ships that ply international voyages.
The Zhoushan port aims to challenge Singapore's dominance of the multi-billion dollar shipping fuel industry, relying on proximity to some of the world's biggest ports and Beijing's policy support to give it an edge.
