This study aims to further strengthen China-Pakistan economic ties and friendly relationship through the analysis of molluscan fisheries in each country. The novelty of this study is based on the first-time economic analysis of long data series, more than six decades, representing molluscan fisheries and the evaluation of the stock status of this resource. In China, molluscan fisheries have flourished because of government?s fisheries encouraging policies. Consequently, molluscan fisheries landings have increased enormously from 1950 (90500 t) to 2014 (2197142 t). In addition to this, reported figures reveal that since 1984, both exports and imports of this fisheries resource have increased considerably in terms of quantity and value. Overall, capture production of molluscs and their contribution to the national economy showed decreasing trend after 2000. This decline is a result of the ongoing open access regime in China, which has resulted in overcapacity. In the past, indeed, efforts have made to manage fisheries resources in China but a majority of them only focused on input based methods. Thus, output based methods have neglected in order to manage fisheries resources. Therefore, as our analysis shows, class cephalopoda, a major landed molluscan class in Chinese marine waters, is overexploited. Considering whole fishing industry in China, for maximum economic utility of this fisheries resource, it is suggested that the annual harvest of this fisheries resource should be between 540000–545000 t. This range should be treated as target reference point. In addition to this, fishing beyond 550000 t should be considered as limit reference point. If the catch goes beyond limit reference point, economic loss will be suffered in the form of diminished resource rent. Similarly, cuttlefish, bobtail squid group, a major landed group of class cephalopoda, is also severely overexploited. For this group, annual harvest between 130000 – 140000 t, target reference point, is recommended. This harvest level is expected to generate maximum economic utility. Moreover, harvest beyond 140000 t, limit reference point, will result in reduced economic gain. Overexploitation should be avoided as it confers several disadvantages such as high cost, low revenue, diminished resource rent etc. The only solution to this problem is not associated with the shift from inshore to offshore and then distant water fishing rather resource conservation should be given due importance coupled with output based management because if there is no fish there will be no economic activity.
