Question: Briefly descape the Self-strengthening Movement and account for it簿 failure.

After the defeat in the

Dpium War & the Arrow Wan, most Chinese Scholar-Officials realizu. the weakness of the Manchu Govem- nent. The Taiping Rebellion furth- er revealed China's weakness & the nilitary auperiority of the forew igners (Ever Victorios Army). Besides, the increased economic activities of foreigners meanta threat to the Chinese sovereignty

hus, they were anxious to avrengthen China by leaning from the west, especially on military & technological skills. The Self- strengthening Movement was the first attempt along such princip les.

The chief aim of the Movement was to recover China's prestige, to check foreign penetration & if possible, to repudiate the Un- tequal Treaties". While keeping. the Chinese traditional moral belief,

the Movement was to app. western military technique & technology for the development industries, communication & com

ierce.

Education in the western style was developed for the train Jing of military, techical & ad- ministrative skills. In addition western languages & science sub- jeats were acquired to supplement Chinese knowledge, The Tungwen- kuan was set up to train interw preters for the Tsungli Yamen. Moveover, students were sent to study abroad...

ECONOMICALLY, New LUSTIISE were developed such as the Tan- chow Cotton mills, the Kalping coalmine & the Foochow shipyard.

Chinese Merchanter Steam Navigat.

ion Company was set up for trans- port of coal & food.,

However, the Self-susong vi -ing Movement proved to be a fail -ure with the defeat of China by Japan in the Sino-Japanese War 18.95 and thus the Movement was stopped. There were several reas sone. for its failure.

Most reformers thought tha.. hey could strengthen China simp). py learning a few westerm methods. of defence. They failed to realiz Jhina should be changed basically. in every way. -- politically (e.g. governmental reforms), economically (e.g. encouraging, industrialisation & modernizatio. and socially (e.g. respect for western leaming & technology). Thus the attempts were fragment. shortsighted instead of for long-term improvement

Besides, there was no overa

Thus olanning for the reforms.3 the changes appeared to be abru, & not well-organised. Moreover,. the efforts were merely those of reforming provincial officers, such as Li, Tso & Tseng. There was little directive guide from the central government. Further- nore, both the central & the local governments lacked capital for the reforms. Thus the over- lependence on merchants for fin- ancial help made the reforms fra -mentary & piece-meal like. In addition there was conflict amori, che leaders. (e,g. Tseng did not rust Li too much for his servin the foreigners in the Ever Vict- ɔrious Army). There were also corruption & embezzlement: among the officials, thus reducing the imount of effective capital for The reforms.

Above all, the movement. greatly lacked the support of the zonservative anti-foreign officia E scholar who were unwilling to accept changes. Empress Dowager, who dominated the court, strongl opposed to the reforms. In fact she used much of the capital fou the Feiyang fleet to build the Summer Palace

Ma Consequently the abrupt. changes failed to strengthen Chin Fundamentally. When China later: *faced an extermal enemy, Japan,

the weakness of the movement was revealed and it was finally stopp ed.
