<h1>Ukraine pushes for inclusion in US-Russia summit talks, rejects land swap proposals under constitutional grounds</h1> The Ukrainian leader is set to meet with the German Chancellor and other European and US officials in Berlin ahead of a planned summit between the US and Russian Presidents. European and Ukrainian leaders seek to ensure their perspectives are considered, as the upcoming summit risks excluding them. Discussions include potential support for Ukraine's development of long-range missile systems unrestricted by Western limitations. The US President has indicated a willingness to consider Ukrainian territorial concessions and land swaps with Russia, proposals firmly rejected by Ukraine as unconstitutional and a threat to sovereignty. European allies emphasize Ukraine's essential role in peace negotiations, wary that exclusion could lead to unfavorable terms favoring Russia. The US administration has shifted its stance on Ukraine's NATO membership and focuses on broader geopolitical interests, including improving US-Russia relations, while maintaining pressure on NATO allies over defense spending and trade tariffs.
