A few Ts need to be crossed to better frame the issue at hand in the article above.
Sixty-five years ago, the Chinese Communist Party successfully wrestled power from the US-supported Chinese Nationalists. Out of humanitarian and political concerns, the US Navy ferried a failed Chinese Nationalist regime to exile on Japanese Taiwan. Chiang Kai-shek had approached General MacArthur about a desirable Japanese exile. On US-occupied Japanese Taiwan, the Japan-friendly Generalissimo got his wish.
Taiwan is presently administered by US-approved, locally elected "Taiwan authorities" (台湾 当局). Ma Ying-jeou, while playing Chinese "zongtong" on Taiwan, obfuscates that he is the locally elected lieutenant-governor Washington picked up as its representative on US-occupied Japanese Taiwan. No internationally recognized Chinese power is presently controlling Taiwan.
Cairo is a footnote to San Francisco. The September 8, 1951 San Francisco Peace Treaty with Japan did not transfer to China the sovereignty of Taiwan. Short of Taiwan, Chinese have no internationally recognized claim to the Senkakus, either. Why is China bitching over the Senkakus? Clearly because Japanese control of the Senkakus foretells an ever possible restoration of Taiwan to Japan along the Okinawa reversion process.
On a Taiwan firmly tethered into the San Francisco status quo, vacuous dreams of Cairo are passé. Those who used Taiwan as stepping-stone to reach safe haven in affluent America ought have the decency to quit pelting comments threads with their insufferable Chinese nationalist prattle.
Those sourpusses' appeal to hate against Japan, while allowing them the vicarious thrill of victory, will not reenact a war their grand-fathers did not win, except by association. Egging Zhongnanhai on to rob Japan of Senkakus will not help it assert its legally unattainable claim to Japanese Taiwan.
Once the above understood, an exchange of commercial and cultural representatives between the two independent, separate customs territories not only looks innocuous but rather highly desirable in that it will legally confirm the mutual foreignness of the two entities.
