China may have to review its policymaking toward both the UK and European Union

If China had been given a vote in the UK referendum on Britain's membership in the 28-nation European Union, it may have voted to stay in. The British electorate, however, chose the Brexit option, sending shivers through international markets.

Chinese shares slipped by 1 percent, reflecting a general global concern about the consequences of the UK vote. The volatility is sure to settle. Economies as large as those of China or the US can cope with the difficulties of their European partner.
