Japan needs China's business and pacified US-China relations
  • An increase in Japan’s exports to China was key to the country’s entirely export-driven 1 percent growth in the first two quarters.

  • But all that could be an easily reversible work-in-progress because Japan is a direct participant in a turbulent U.S.-China relationship.

  • China has kicked the door ajar and is now watching how Japan will behave in a maelstrom of Washington-Beijing dealings.

There are few, if any, world leaders that could match the clarity of Japan Prime Minister Shinzo Abe China strategy.

Having led the Liberal Democratic Party to a resounding election victory, Abe declared in December 2012 that " China is an indispensable country for the Japanese economy to keep growing. We need to use some wisdom so that political problems will not develop and affect economic issues."

That was very clear, but the implementation of that strategy sounded like squaring a circle.

Over the next six years, Abe tried everything. Pressed by his virulently anti-Chinese constituency, and encouraged by the Obama administration's China-hostile "pivot to Asia," Abe started out with confrontation and direct competition with China's search for an expanding global footprint.

Realizing the futility of that approach, he hesitantly changed to a more cooperative and friendlier posture — effectively turning into a supplicant for contact and attention with an aloof, hostile and indifferent Chinese leadership.

Abe's original mistake cost him trust — the most precious asset in dealing with China.

China is testing

The Japanese prime minister's state visit to China last week was therefore a triumph of persistence — six years of an incredible political tour de force.

Careful, though. Abe is on probation (just take a look at that handshake at the Diaoyutai State Guesthouse). China is now testing how far a more constructive relation with Japan may go in the context of a rapidly changing geopolitical landscape. The Chinese know that Abe flunked a similar test with Russia , which will probably cost him one of the apparently dearest objectives of his political career.

And beware this red herring: The idea that Beijing suddenly warmed up to closer relations with Japan as a result of China's weakening economy and a trade dispute with the U.S. is arrant nonsense.

In fact, China's economy is in good shape. The gross domestic product growth was 6.7 percent in the first three quarters of this year. Inflation is stable (2.5 percent in September), public finances are sound (a budget deficit of 3 percent of GDP and public debt of $5.2 trillion, or 47.6 percent of GDP), and there is a trade surplus on goods and services of $70 billion, with a whopping $3 trillion stashed in foreign exchange reserves.
