The workers from the Nantong shipyard owned by the troubled Rongsheng Heavy Industries have been on strike since Sunday after the company announced that they had to go on forced leave for a week.

The workers" strike comes after Rongsheng reported a loss of 49 million yuan (U.S.$8 million) in the first quarter of 2013, citing "the most difficult time yet" in the two recent quarters, shipping website SinoShip News said.

Lei Dong, secretary to Rongsheng"s president, told the paper the layoffs are not a sign of financial trouble at the shipbuilder, but were rather the result of "restructuring," saying more than half the employees who were laid off were subcontractors and the remainder full-time employees.

Two Chinese newcomers make the ranking: TongKun Group at 48 and Hengyi Petrochemical at 50. Both are polyester producers that make their own raw materials. Hengyi also has a large, integrated nylon 6 business. Both companies join similar Chinese firms, like Hengli Petrochemical and Rongsheng Petrochemical. All these companies have been building massive complexes for aromatics and derivatives, in many cases swamping entire segments of the chemical industry—such as purified terephthalic acid—with new capacity that is well beyond the scale of players outside China.

A Rongsheng Petrochemical subsidiary, Zhejiang Petroleum & Chemical, started up the second phase of its massive refining and petrochemical complex in Zhejiang, China, in 2021. With capacity now doubled, the facility can process 40 million metric tons (t) of oil per year. The facility has a large petrochemical output: up to 6.6 million t of aromatics and 1.4 million t of ethylene per year. The expansion allowed the company to start making specialized polymers, such as acrylonitrile-butadiene-styrene and polycarbonate.

Asahi Kasei has been making a push into biobased chemicals. It plans to make the building-block chemical acrylonitrile from biomass-derived propylene at its Tongsuh Petrochemical subsidiary in South Korea. It will use a mass-balance approach, in which biomass fed into a conventional petrochemical plant is credited to a share of products that are made. And at a conference in Washington, DC, in March, company officials said Asahi would commercialize nylon 6,6 made with biobased hexamethylenediamine from Genomatica. Meanwhile, the Japanese company is exiting one of its old-line operations. In August, the company said it was leaving the clear styrene block copolymer business by 2023 because of deteriorating profitability.
