New Delhi, Dec 16 : Prime Minister Narendra Modi on Wednesday accepted the invitation of British Prime Minister Boris Johnson to be part of the G7 meeting chaired by the UK in 2021, seeking to build a wider alliance against China's growing power. British Foreign Secretary Dominic Raab handed over a letter from Johnson, inviting the Prime Minister to the G7 meeting. Modi thanked Raab and accepted the invitation, the Prime Minister's Office (PMO) confirmed in a statement on Wednesday. The development comes after Johnson's office earlier announced that it had extended the offer to Indian, South Korean and Australian leaders to take part in the G7 meeting, "delivering the Prime Minister's ambition to work with a group of like-minded democracies to advance shared interests and tackle common challenges". Recalling his recent telephone conversation with British PM, Modi stressed the importance of the India-UK partnership in the post-Covid world. He called for an ambitious and outcome-oriented 360-degree roadmap covering trade and investment, defence and security, migration and mobility, education, energy, climate change and health, in order to tap the full potential of the bilateral relationship. Modi also conveyed his keenness to receive Johnson in New Delhi next month, on the occasion of India's 72nd Republic Day celebrations. During his visit, Johnson will be just the second British leader since Indian independence to attend India's Republic Day parade in New Delhi as a guest of honour, after John Major in 1993. Despite conveying greetings of Johnson to Modi, the British Foreign Secretary thanked him for participating in the recently held Climate Ambition Summit co-hosted by the UK. Raab also stressed the priority that the UK government's attaches to elevating relations with India, based on "shared values and interests and the potential to address common global challenges together". Britain's relationship with China has slid to its most confrontational levels in a generation, chiefly because of the national security law Beijing has imposed in Hong Kong and London's decision to ban 5G network services by Huawei Technologies, which it contends is closely linked to the Chinese government. Increasing concerns over China's assertive moves in the Indo-Pacific have also resulted in greater diplomatic efforts in the region by the US, Britain and the European Union - with India, Australia and the 10-nation Asean group at the forefront of their focus. /IANS
