China and Japan plan to resume military exchanges this year and may hold mutual naval visits, the Financial Times reported. If it goes through, the plan would see Japanese warships enter Chinese ports for the first time since the second world war. The renewed push to build ties between the two most powerful military forces in the region underlines a considerable improvement in Sino-Japanese relations since Prime Minister Shinzo Abe took over the government last year. After a three-year break, the two governments resumed high-level defense meetings in November. A Japanese warship visiting China would be a large symbolic gesture of improved bilateral ties.
