compare the democratic system in china with mexico...

Mexico: Since its independence in 1930, Mexico holds elections after every six years to elect its President. The country has never been under a military or dictator’s rule. But until 2000 every election was won by a party called PRI (Institutional Revolutionary Party). Opposition parties did contest elections, but never managed to win. The PRI was known to use many dirty  tricks to win elections. All those who were employed in government offices had to attend its party meetings. Teachers of government schools used to force parents to vote for the PRI. Media largely ignored the activities of opposition political parties except to criticise them. Sometimes the polling booths were shifted from one place to another in the last minute, which made it difficult for people to cast their votes. The PRI spent a large sum of money in the campaign for its candidates.

China :  In China, elections are regularly held after every five years for electing the country’s parliament, called Quanguo Renmin Daibiao Dahui (National People’s Congress). The National People’s Congress has the power to appoint the President of the country. It has nearly 3,000 members elected from all over China. Some members are elected by the army. Before contesting elections, a candidate needs the approval of the Chinese Communist Party. Only those who are members of the Chinese Communist Party or eight smaller parties allied to it were allowed to contest elections held in 2002-03. The government is always formed by the Communist Party.
