Aren't the Rohingya's from Rakhine state, on Burma-Bangladesh border? Why do they need to go all the way accross Myanmar to take refuge in China, when Bangladesh a Muslim country is just across the border?
Because Indian installed puppet dictator Hasina does not allow them in, under Indian instruction. Bangladesh need to make a comprehensive deal with Myanmar under supervision of ASEAN, OIC and China, so that we can take them in. We cannot afford to have bad relation with Myanmar, we need to solve this Rohingya issue with Myanmar at whatever cost.

Arakan used to be a vassal of Bengal Sultanate for centuries, long before it was conquered by Myanmar king around 1785. This happened because of the fall of Bengal to British in 1757 and the British did not look after Bengal's Vassals, but after 41 years, it was taken over by the British in 1826. British in 1947 decided to give Arakan to Burma.
The Rise of Islam and the Bengal Frontier, 1204–1760
"The reigns of Sultan ‘Ala al-Din Husain Shah (1493–1519) and his son Nasir al-Din Nusrat Shah (1519–32) are generally regarded as the “golden age” of the Bengal sultanate.[
90] In Husain Shah’s reign, for example, Bengali Hindus participated in government to a considerable degree: his chief minister (
vazīr), his chief of bodyguards, his master of the mint, his governor of Chittagong, his private physician, and his private secretary (
dabīr-i khāṣ) were all Bengali Hindus.[
91] In terms of its physical power and territorial extent, too, this was the sultanate’s high tide. In the second year of his reign, 1494, Sultan Husain Shah extended the kingdom’s northern frontiers, invading and annexing both Kuch Bihar (“Kamata”) and western Assam (“Kamrup”).[
92] Writing around 1515, Tome Pires estimated this monarch’s armed forces at a hundred thousand cavalrymen. “He fights with heathen kings, great lords and greater than he,” wrote the Portuguese official, “but because the king of Bengal is nearer to the sea, he is more practised in war, and he prevails over them.”[
93]
The king thus managed to make a circle of vassals of his neighbors: Orissa to the southwest, 
Arakan to the southeast, and Tripura to the east.[94]
But the palmy days of independent Bengal were numbered. Even as the Husain Shahi dynasty was taking root, Babur, a brilliant Timurid prince, was rising to prominence in Central Asia and Afghanistan. In 1526, resolving to make a bid for empire in North India, Babur led his cavalry and cannon through the Khyber Pass and overthrew the Lodi dynasty of Afghans, the last rulers of a vastly shrunken and decayed Delhi sultanate. As a result of this triumph, defeated Afghans moved down the Gangetic plain and into the Bengal delta, where they were hospitably received by Nasir al-Din Nusrat Shah.[
95] Thus the span of a century from the death of Jalal al-Din Muhammad (d. 1432) to that of Nasir al-Din Nusrat Shah (d. 1532) witnessed a wholesale transformation of Bengal’s political fabric. In the reign of the former sultan, descendants of old Turkish families had still formed the kingdom’s dominant ruling group. But in the following century the scope of Bengali participation at all levels of government continually widened, while the throne itself passed from Indo-Turks, to East Africans, to an Arab house, and, finally, to Afghans."
