Japan is set to become a more demanding US ally in the wake of the Democratic Party of Japan's historic election win, analysts in Washington and Beijing contend.
The prospect of the shift in power in Tokyo inspires a measure of wariness in both foreign capitals.
But while the US hopes, in the words of the official state department response to the DPJ win, to “work with the new government [to] further cement this indispensable alliance”, the result has been met with cautious optimism in Beijing. Chinese officials hope to see greater regional engagement from the world's second-largest economy and less of a focus on closer US-Japanese ties.
