Well !

Im from Pakistan manufacturer and exporter of stain less steel surgical and dental instruments.
Having look at my web at ALI BABA.COM, a person XIN SU from China whom full information I don't like to disclose here, made contact me through ALI BABA'S TRADE MANAGER and asked the prices of some of my products and intended to give a big order of those. I started negociating with him and he very soon became satisfied with prices I quoted him. I asked him about the mode of payment but he didnot answer me of that. I asked him repetedly but all the time he called me to come toChina to sign a contract. I demanded from him invitation letter but he refused and advised me to have visitor visa,it shocked me and I got a point.I at once searched the company at net whose he showed the representative.I got surprised to see the list of people and their bad comments about that company. I send him all that links from net but he denied all that and  very cleverly send me a bogus purchase order and invitation letter. I persued the company through my friends there in China, no such a company was there and the tel nums he gave me was no in any use.I really waisted my time in negociating and leaving my other jobs.
The same happened from a person from Nigeria. He was also fraud but I recognize him soon.
A number of people asked me the prices negociate regular and long but all of them are ......... . One should remain cool and calm while he/she want to live in business,wahat ever other do it dose not effect our efforts and emotions. Inspite of all that I do like China and love Chinese,they are our well wisher. May Pakistan and China live long.(Amen)
