WTO members signed the covenant to grant China market economy status automatically after 15 years upon joining WTO.  If WTO members don't grant China the market economy status, they're showing the world their non-credibility and despicability because they don't honour the contract they sign.

Japan has shown that it is non-credible and despicable because it won't honour the contract it signs.  Let's see who are non-trustworthy in WTO.
