Curzon and Younghusband were reprimanded by the Secretary of State for India and the foreign secretary in London for not understanding that to involve the Tsarist Empire in the encirclement of the Kaiser’s Germany, an understanding had been reached that, at the outbreak of hostilities in Europe, Russia would open a second front against Germany. The understanding also pledged that both Britain and Russia would keep their hands off Tibet. Curzon broke that pledge and, in consequence, found his second term as Viceroy aborted. The Treaty of Lhasa that Younghusband had squeezed out of the Tibetans was largely repudiated by London, its harshest clauses substantially diluted. Indeed, the British government of India was determined to bring the Chinese into, not keep them out of, the subcontinent’s affairs. In the 1890s, they tried their utmost to get the Chinese empire to do its “duty” to guard its long border in Aksai Chin with Central Asia but failed. The Brits insisted on a Chinese presence at every settlement made by them that involved Tibet, from the 1893 trade agreement to the Darjeeling settlement to the Simla conference of 1914. So wedded were the Brits to Chinese sovereignty/suzerainty over Tibet that Sir Henry MacMahon did not attempt to get the eponymous MacMahon Line inscribed on the Survey of India’s official maps. That was accomplished only in 1932 at British Indian foreign secretary Sir Olaf Caroe’s instance. And yet, Zhou Enlai virtually accepted the MacMahon Line in his proposals for a border settlement presented to Nehru in April 1960. And after the Chinese in 1962 had reached the Brahmaputra valley, their troops were unilaterally withdrawn behind most of the MacMahon Line, even from Tawang, if not from Thagla Ridge.
