Big events, no matter where they are held, always draw attention, and criticism. The upcoming G20 summit in Hangzhou, East China's Zhejiang province, is no exception. Speculations have been rife over the mega-diplomatic event - from the cost of hosting the summit to the strengthening of security measures.

The Hangzhou local government has vowed to host the big event at the lowest possible cost. True to its promise, it has not even built a new conference hall. Instead, it has just upgraded and renovated existing buildings to showcase Chinese architecture.

Speculations on the strengthening of security in the city, however, are uncalled for, because cities across the globe that play hosts to important international events have to beef up security, especially because of the growing risk of terrorist attacks. And as the host country, China cannot take any chances with the security of the delegates to the summit that will comprise 20 heads of state or government.
