En kinesisk rådgiver går inn for at Kina bruker sin makt som Japans største kreditor til å tvinge Japan til underkastelse.
Skulle Kina ta ham på ordet kan det får store konsekvenser, også for Kina.
Jin Baisong from the Chinese Academy of International Trade – a branch of the commerce ministry – said China should use its power as Japan’s biggest creditor with $230bn (£141bn) of bonds to “impose sanctions on Japan in the most effective manner” and bring Tokyo’s festering fiscal crisis to a head.
Writing in the Communist Party newspaper China Daily, Mr Jin called on China to invoke the “security exception” rule under the World Trade Organisation to punish Japan, rejecting arguments that a trade war between the two Pacific giants would be mutually destructive.
Separately, the Hong Kong Economic Journal reported that China is drawing up plans to cut off Japan’s supplies of rare earth metals needed for hi-tech industry.
The warnings came as anti-Japanese protests spread to 85 cities across China, forcing Japanese companies to shutter factories and suspend operations.
Fitch Ratings threatened to downgrade a clutch of Japanese exporters if the clash drags on. It warned that Nissan is heavily at risk with 26pc of its global car sales in China, followed by Honda with 20pc. Sharp and Panasonic both have major exposure. Japan’s exports to China were $74bn in the first half of this year. Bilateral trade reached $345bn last year.
Mr Jin said China can afford to sacrifice its “low-value-added” exports to Japan at a small cost. By contrast, Japan relies on Chinese demand to keep its economy afloat and stave off “irreversible” decline.
“It’s clear that China can deal a heavy blow to the Japanese economy without hurting itself too much,” he said. It is unclear whether he was speaking with the full backing of the Politburo or whether sales of Japanese debt would do much damage. The Bank of Japan could counter the move with bond purchases. Any weakening of the yen would be welcome.
A recent study by the US Defence Department concluded that a Chinese firesale of US debt was not a serious threat.
Beijing hints at bond attack on Japan
A senior advisor to the Chinese government has called for an attack on the Japanese bond market to precipitate a funding crisis and bring the country to its knees, unless Tokyo reverses its decision to nationalise the disputed Senkaku/Diaoyu islands in the East China Sea.
