In international relations, states make alliances on their national interests. In the 20th century, most of the states made alliances on geostrategic lines, especially military related matters. During the cold war, there were two blocs; Western led Nato alliance and USSR led Warsaw pact. After the dissolution of the USSR, America became the sole superpower - unquestioned over her actions.
After 2010, China became the 2nd largest economy in the world, posing a challenge to American supremacy. BRI (Belt and Road Initiative) by China is the largest infrastructure development in the world covering about 130 states, including most of the Western states. It has negatively impacted the economy of America, which is declining day by day.
China’s policies have attracted the foreign companies to establish their businesses in China. To end American monopoly over finance related matters, China has established “Asian Infrastructure Investment Bank”, in parallel to The World Bank. Through this bank, China is lending borrowings to the developing states connected via BRI for infrastructure development by Chinese contractors.
America has pressured her allies to work on “Contain China” policy and to be limited with China. To counter BRI influence, G7 states have made an agreement to launch B3W (Build Back Better World) infrastructure development. It is pertinent to mention here that Pakistan has refused to host American military bases for surveillance in Afghanistan. Moreover, Pakistan is determined to complete the BRI project in Pakistan as CPEC (China Pakistan Economic Corridor), which is the shortest way from China to the Indian Ocean via Gwadar port.
