import restrictions in response to the japanese nuclear power plant accident in june 2013 japan raised concerns over restrictions on japanese food exports in the wake of the fukushima incident. following the incident japan had been closely monitoring food products for the presence of radionuclides and as of april 2012 had imposed a food intervention exemption level of 1msv year - equivalent to the codex standard. however the dietary exposure estimates from total diet studies were far below 1 msv year across all studies - including those completed in fukushima prefecture. based on this scientific data japan requested all members to lift any import restrictions on japanese exports. japan thanked those members that had already lifted most or all such measures but noted that china hong kong china and chinese taipei continued to maintain import bans on many japanese food exports. japanese foods placed on the market were safe for human consumption without any extra control measures nonetheless japan was willing to certify compliance with the radionuclide regulation for each consignment as a provisional measure. hong kong china and chinese taipei had already begun to analyse the monitoring data provided by japan and japan looked forward to the opportunity the meet with china regarding this trade concern. chinese taipei explained that although japanese food exports contained acceptable trace levels of radionuclides those levels still raised concern for chinese taipei and its consumers consumer protection groups and legislators. in order to assuage these concerns chinese taipei requested further information from japan including about its surveillance methodology and control measures. chinese taipei also requested that foods exported from the five restricted prefectures be accompanied by a certificate of origin and a pre-export laboratory report certifying that they had been tested for radioactivity. the relevant supplementary documents had been received from japan on 13 june 2013 and were under review. chinese taipei expressed its desire to continue normal communications and co-operation with japan in the future. hong kong china explained that its import restrictions were based on public health concerns over food imported from the five affected prefectures in japan. it was waiting for further information from japan in order to fully assess the threat level presented by japanese imports. hong kong china stated that it would continue to monitor information from japan and other relevant international organizations and would adjust its import measures according to any new updates. china responded that it only restricted the import of products produced in seriously nuclear-contaminated areas and those products seen as high-risk. the detection of nuclear contamination in food and agricultural products in japan had been on-going. china requested that japan urge its relevant departments and enterprises to take measures that would ensure all food and agricultural exports were uncontaminated by nuclear matter and could satisfy the chinese national standards. japan explained that the detection of nuclear contamination in agricultural and food products noted by china only occurred in products that were not legally released to the market. japan continued to monitor these products. in march 2014 japan reiterated its concern over import restrictions by china on japanese food exports mainly food and feed following tepcos nuclear power station incident. china maintained the ban on all types of food and feed from 10 prefectures in japan and requested the submission of an official pre-test certificate for fruits vegetables milk products medicinal plants and fishery products from all other prefectures. japan considered that these measures were more trade restrictive than necessary and not based on the relevant international standard. furthermore china had not yet approved the form for the requested certificate. japan requested that china expeditiously finalize its analysis of the proposed certi
