BJP on Saturday blamed the government for for its ‘weak’ China policy and demanded a pro-active approach to protect India's sovereignty.

"When China was building pressure through incursions --1,040 times last year and 270 times this year besides incursions by helicopter -- to establish itself as a superpower, New Delhi was regrettably terming it as a media hype," BJP chief Rajnath Singh told a press conference here.

Claiming that a Chinese think tank had advised Beijing to split India into 25 to 30 pieces, he demanded a pro-active China policy to protect the sovereignty of the country.

While there was no Sino-India border dispute after the tripartite agreement between India, China and Britain leading to demarcation of McMohan line, it has surfaced now because of the ‘weak’ policy of the Centre, he said.

"If China continues its hegemonistic policy, a 1962-like situation cannot be ruled out," the BJP chief said.

Referring to the proposed diversion of the Brahmaputra by China, he said India should force it to sign a water treaty.

The diversion, if executed, would affect Assam, Arunachal Pradesh and Bangladesh.

Singh also criticized the US for tripling its aid to Pakistan even after the admission by President Barack Obama that the assistance was being misused against India.

Bangladeshi infiltration, he said, posed a serious threat in the North East, particularly in Arunachal Pradesh, whose demography would change if the Centre does not take action.
