KARACHI - Partial and biased rejection of Chinese firm in multi-million contract causes strain in Sino-Pakistan business relationship, says a press release. Pakistan and China will commence celebration of their 60th anniversary of bilateral relations this year on May 21 in a befitting manner demonstrating the unique and all weather relationship between the two countries. A French company flirted with Security Papers Limited (SPL is a Joint venture of GOP-Turkey-Iran) making budgetary offers but refusing to participate in international bidding citing law and order, security measures, tender conditions and lack of French insurances. Hubei MingFeng producer and seller of pulp to the 50,000 metric tons Chinese state owned banknote industry stepped in to create competition in an earlier monopoly market. The Chinese firm also invited a delegation from SPL and showed them their pulp production facilities serving the quality conscious and growing Chinese banknote industry. Discussions with the General Manager of the Chinese firm through an interpreter reveal that entire SPL delegation including consultant were impressed with the ground realities as evidenced in the visit report. Numerous technical exchanges took place but all of a sudden they were served with a notice of technical non-compliance.
