The Senkaku/Diaoyu Island Dispute: Part One

By Nicole Boyd

This is the first part of a three-part series on the disputed territory in the East China Sea. Stay tuned for parts two and three!

The Issue

Arguments are heating up in the East China Sea over the disputed sovereignty of the Senkaku/Diaoyu Islands. The islands represent a long-standing territorial dispute between China, Japan, and Taiwan. Tensions have increased as a result of the Japanese government’s purchase of the islands from private ownership, straining relations between the nations. This is a delicate situation for the United States, which officially maintains a neutral position but stands by the islands’ inclusion in the 1960 U.S.-Japan security treaty, which would require the U.S. to support Japan in any military dispute concerning the islands. Mismanaging the situation could result in damaged relations with all parties involved. I seek to outline the history of the dispute, its current significance and political implications, as well as recommend that the U.S. continue to maintain its neutral position regarding the sovereignty over the islands, provide military support to Japan under the 1960 security treaty, and promote diplomacy and restraint rather than economic or military retaliation in resolving the dispute.

Conflicting Claims



The disputed islands, called the “Senkaku” in Japanese, and the “Diaoyu” in Chinese, are a small chain of 5 islands and 3 barren rocks located in the East China Sea. The islands were administered by Japan from 1895 to 1946, when they were transferred to U.S. control following World War II under the San Francisco Treaty between Japan and the allied powers. In 1972 the U.S. returned control of the islands to Japan.


Japan makes the following arguments for its rightful claim to the territory:


1. Japan surveyed the land in 1894 and determined that it was Terra Nullius, or “land belonging to no one.”The cabinet then formally decided to incorporate the islands into its territory in 1895 on the principle of discovery and acquisition as its right under widely accepted conventions of international law.
2. China did not administer the region nor dispute Japan’s claim prior to 1971 when the U.S. began preparing to transfer control to Japan.

3. The islands were never a part of Taiwan or administered by the Chinese government, thus are not contained in the Treaty of Shimonoseki in which China ceded control of “The island of Formosa [Taiwan], together with all islands appertaining or belonging to the said island of Formosa” following the end of the first Sino-Japanese war in 1895. As a result, the islands were not included in the San Francisco Treaty of 1951 in which Japan renounced control of Taiwan.


Both the People’s Republic of China (PRC) and the Republic of China (ROC) dispute Japan’s territorial control of the islands.  As each claim that they are the rightful seat of the Chinese government, they make the same arguments for “Chinese” rights to the islands:


1. China had knowledge of the islands in documents and maps as far back as the 14th century, thus refuting Japan’s claim on the basis of Terra Nullius.
2. China argues that the islands were included in the 1895 Treaty as part of Taiwan, and thus were included in the San Francisco Treaty and should have been returned to China with Taiwan.

3. In 1971 China used this argument to formally oppose the island’s return to Japan by the U.S.

These arguments are still widely disputed. The current U.S. position is one of neutrality, but with the affirmation that it will hold to the U.S.-Japan Treaty of 1960 with respect to the islands, which calls for the U.S. to help defend Japan against military attacks to its territory.
