The firm sounds a warning, however, over the specialty/salt chemical division, saying that while performance was stable "overall", individual products were "varied".
HaiKe's Executive Chairman, Xiaohong Yang, said the firm was adjusting to improve its margins: "The Board remains conscious of a continuing difficult global economic environment and great emphasis has been placed on tightening costs and increasing operational efficiencies to strengthen the business."
In the last 12 months HaiKe has lost 49% of its value.
