This warning was voiced by an unnamed high-ranking officer of the People's Liberation Army during a meeting with a group of senior Japanese politicians, a source, who spoke on condition of anonymity, told the Japan Times.
"Japan will have no future if it only follows the United States," a source quoted the PLA officer, working at the China Institute for International Strategic Studies (CIISS), as saying.
The CIISS is a think tank tasked with offering policy advice to the Chinese government and the military based on the analysis of global affairs, China's national security and economic matters.
The delegation, headed by Masahiko Komura of the ruling Liberal Democratic Party of Japan, spoke to the CIISS experts last week. Komura declined to specify what the two parties discussed following the talks but said that the conversation was "very frank," as per the media outlet.
The revised guidelines reflect the shift to a more assertive role the Japanese armed forces could and aspire to play in the world, as well as Washington's backing thereof.
China views the latest developments as a change that could affect regional balance of power and an initiative targeted against Beijing amid rising tensions over the Diaoyu/Senkaku islands, claimed by both Asian nations.
