They do make excellent products, those duplicate inferior electronic goods and toys which are available throughout the India are not the only thing China manufactures. They do manufacture high end toys and all our good electronics are also manufactured in China. Even Mumbai metro is also using the rolling stock from China.
Now China exports their used locos and rolling stocks to Pakistan railways and the Pakistanis readily buy them. That is totally political and economical issue as PR can't spend lots of money to buy new equipments they satisfy themselves with the used equipments and that is another reason for PR's faliure. Most of their locos have stopped working.
